When I type in the first textbox, it should run a conversion which appears in the second, and when I type in the second, it will appear in the first. However, when I type in the first textchanged event, it triggers the second, which disrupts entering in the first and vice versa. Is there a way I can disable firing the textchanged event when it is highlighted or something?
public void dB10_TextChanged(object sender, EventArgs e)
{
TextBox dB10 = sender as TextBox;
double dBV;
int i = dB10.Text.Trim().Length;
if (i > 0)
{
dBV = Convert.ToDouble(dB10.Text);
}
else
return;
UnitConverter dBConverter = new UnitConverter();
// Controls for if various radiobuttons were clicked
if (dBVRadio.Checked == true)
{
dBV = dBConverter.dBVToVolts(dBV);
voltage.Text = dBV.ToString();
}
else if (dBuRadio.Checked == true)
{
dBV = dBConverter.dBuToVolts(dBV);
voltage.Text = dBV.ToString();
}
}
public void voltage_TextChanged(object sender, EventArgs e)
{
TextBox voltage = sender as TextBox; //V >> dB10 (dBV/dBu)
int i = voltage.Text.Trim().Length;
double volts;
if (i > 0)
{
volts = Convert.ToDouble(voltage.Text);
}
else
return;
UnitConverter dBConverter = new UnitConverter();
if (dBVRadio.Checked == true)
{
dBuRadio.Checked = false;
volts = dBConverter.voltsTodBV(volts);
dB10.Text = volts.ToString();
}
else if (dBuRadio.Checked == true)
{
volts = dBConverter.voltsTodBu(volts);
dB10.Text = volts.ToString();
}
}
you can remove the handler of another textbox and then add it
public void dB10_TextChanged(object sender, EventArgs e)
{
voltage.TextChanged-= voltage_TextChanged;
TextBox dB10 = sender as TextBox;
double dBV;
int i = dB10.Text.Trim().Length;
if (i > 0)
{
dBV = Convert.ToDouble(dB10.Text);
}
else
return;
UnitConverter dBConverter = new UnitConverter();
// Controls for if various radiobuttons were clicked
if (dBVRadio.Checked == true)
{
dBV = dBConverter.dBVToVolts(dBV);
}
else if (dBuRadio.Checked == true)
{
dBV = dBConverter.dBuToVolts(dBV);
}
voltage.Text = dBV.ToString();
voltage.TextChanged+= voltage_TextChanged;
}
You can just use a bool variable:
bool escape = false;
public void dB10_TextChanged(object sender, EventArgs e)
{
if(escape)
return;
escape = true;
// your code
escape = false;
}
public void voltage_TextChanged(object sender, EventArgs e)
{
if(escape)
return;
escape = true;
// your code
escape = false;
}

i want after payment process go to the form main.

If you call some code from main then it will return to main when the call is finished. In the case of a Form, it's handled on a different thread started from main. The thread will never return back to main in this context. If you are using a click event to do some action and want to call some other code when that happens, then you need to re-design your infrastructure. Look into SOLID development principles and dependency injection.

I have textbox and when i create that form i pass some values and then i prevent user to input some things into textbox based on passed values with this code:
private void textBox1_KeyPress(object sender, KeyPressEventArgs e)
{
if (!brojevi && char.IsDigit(e.KeyChar))
{
e.Handled = true;
return;
}
if (!slova && char.IsLetter(e.KeyChar))
{
e.Handled = true;
return;
}
if (!znakovi && char.IsPunctuation(e.KeyChar) || !znakovi && char.IsSymbol(e.KeyChar))
{
e.Handled = true;
return;
}
if (!razmak && char.IsSeparator(e.KeyChar))
{
e.Handled = true;
return;
}
if (maxKaraktera != -1 && (textBox1.Text.Length + 1) > maxKaraktera)
{
e.Handled = true;
return;
}
if (String.IsNullOrWhiteSpace(textBox1.Text))
{
return;
}
if (maxBroj != -1 && Convert.ToDouble(textBox1.Text) > maxBroj)
{
e.Handled = true;
return;
}
}
Problem is that i enabled brojevi and set maxBroj to 10
Now when i try typing some char, it checks and see that slova is not true, set e.Handled = true and return and in my textbox that char is not imputed which is ok.
But when i try inserting number which is greater than 10 (let's say 12), it goes to if statement where it checks if(maxBroj != -1 && Convert.ToDoube(textBox1.Text) > maxBroj) and it enters it, set e.Handled = true and return but number is implemented in textbox.
Why this happens?
EDIT: Code from creating form and form that has textbox
Creating from:
MessageBoxWithValue msg = new MessageBoxWithValue("Unesite kolicinu", "Unesite zeljenu kolicinu. Maksimum: " + aa.maxKolicina.ToString());
msg.brojevi = true;
msg.maxBroj = aa.maxKolicina;
msg.ShowDialog();
if(msg.DialogResult == DialogResult.OK)
{
kol = Convert.ToDouble(msg.returnValue);
}
else
{
return;
}
Here is MessageBoxWithValue form:
public partial class MessageBoxWithValue : Form
{
public bool brojevi = false;
public bool slova = false;
public bool znakovi = false;
public bool razmak = false;
public double maxBroj = -1;
public int maxKaraktera = -1;
public string returnValue;
public MessageBoxWithValue(string naslov, string opis)
{
InitializeComponent();
this.Text = naslov;
label1.Text = opis;
}
private void textBox1_KeyPress(object sender, KeyPressEventArgs e)
{
if (!brojevi && char.IsDigit(e.KeyChar))
{
e.Handled = true;
return;
}
if (!slova && char.IsLetter(e.KeyChar))
{
e.Handled = true;
return;
}
if (!znakovi && char.IsPunctuation(e.KeyChar) || !znakovi && char.IsSymbol(e.KeyChar))
{
e.Handled = true;
return;
}
if (!razmak && char.IsSeparator(e.KeyChar))
{
e.Handled = true;
return;
}
if (maxKaraktera != -1 && (textBox1.Text.Length + 1) > maxKaraktera)
{
e.Handled = true;
return;
}
if (String.IsNullOrWhiteSpace(textBox1.Text))
{
return;
}
if (maxBroj != -1 && Convert.ToDouble(textBox1.Text) > maxBroj)
{
e.Handled = true;
return;
}
}
private void button2_Click(object sender, EventArgs e)
{
this.DialogResult = DialogResult.Cancel;
this.Close();
}
private void textBox1_KeyDown(object sender, KeyEventArgs e)
{
if(e.KeyCode == Keys.Enter || e.KeyCode == Keys.Return)
{
Uspesno();
}
}
private void button1_Click(object sender, EventArgs e)
{
Uspesno();
}
private void Uspesno()
{
this.DialogResult = DialogResult.OK;
returnValue = textBox1.Text;
}
}
But when i try inserting number which is greater than 10 (let's say 12), it goes to if statement where it checks if(maxBroj != -1 && Convert.ToDoube(textBox1.Text) > maxBroj) and it enters it, set e.Handled = true and return but number is implemented in textbox.
I hope I've got your issue right. You are trying to filter numbers by their values (e.g. maxBroj is set to 10) and you are expecting
if (maxBroj != -1 && Convert.ToDouble(textBox1.Text) > maxBroj)
{
e.Handled = true;
return;
}
not to allow entering a number >10. Unfortunately this will not work as intended, since textBox1.Text won't be set until the KeyPress event handler has finished.
Let's say you are entering 14. When the first KeyPress event is raised (1), textBox1.Text is empty. You are returning from
if (String.IsNullOrWhiteSpace(textBox1.Text))
{
return;
}
Afterwards textBox1.Text is set to "1". Then the second KeyPress event is raised. textBox1.Text is "1", hence the method won't enter the block
if (maxBroj != -1 && Convert.ToDouble(textBox1.Text) > maxBroj)
{
e.Handled = true;
return;
}
Afterwards textBox1.Text will be set to "14", but this is too late for your validation.
You'll have to calculate the expected new value. Please see this question on how to insert the new character in the existing string.
I am new to C#. I need the text of lblBalance to remain as it is when the btnNew is clicked, while it changes according to some calculatios when btnCalc is clicked. Here is my attempt so far.
FIGURED IT OUT, Thanks!
private void btnReset_Click(object sender, EventArgs e)
{
//Reset balance to 0.
balance = 0m;
lblBalance.Text = "";
tbDate.Text = "";
//Call the setupForm procedure.
setupForm();
}
private void setupForm()
{
//Setupform done once to reduce amount of times code must be entered.
//Code to clear these entries and set radio and checkboxes to false.
tbDate.Text = "";
tbAmount.Text = "";
rDeposit.Checked = false;
rWithdrawal.Checked = false;
rFee.Checked = false;
chkBank.Checked = false;
//Return focus to the date textbox
tbDate.Focus();
}
private void btnNew_Click(object sender, EventArgs e)
{
//Clear form, but retain balance when clicked.
setupForm();
}
private void tbDate_TextChanged(object sender, EventArgs e)
{
}
private void lblBalance_Click(object sender, EventArgs e)
{
}
private void btnCalc_Click(object sender, EventArgs e)
{
decimal Amount;
Amount = decimal.Parse(tbAmount.Text);
if ((rDeposit.Checked == true) && (chkBank.Checked == true))
{
Decimal.TryParse(lblBalance.Text, out balance);
lblBalance.Text = Convert.ToString(balance + Amount);
}
else if ((rWithdrawal.Checked == true) && (chkBank.Checked == true))
{
Decimal.TryParse(lblBalance.Text, out balance);
lblBalance.Text = Convert.ToString(balance - Amount);
}
else if ((rFee.Checked == true) && (chkBank.Checked == true))
{
Decimal.TryParse(lblBalance.Text, out balance);
lblBalance.Text = Convert.ToString(balance - Amount);
}
if ((rDeposit.Checked == false) && (rWithdrawal.Checked == false) && (rFee.Checked == false))
{
MessageBox.Show("ERROR: You must select Deposit, Withdrawal, or Service Fee.");
}
}
private void rDeposit_CheckedChanged(object sender, EventArgs e)
{
}
}
}
change:
lblBalance.Text += balance.ToString();
to
lblBalance.Text = balance.ToString();
Inside your btnNew_Click event
That's my code below and it works perfectly fine, except there is one thing that doesn't work correctly. When I click two buttons to match, they should stay visible until the user clicks a third button. How can I do that? Thank you.

As far as I can see, your timer1_Tick handler performs the hiding automatically when it's time period expires. In case you want this hiding to happen manually when third card is clicked, you should not hide the buttons there, but should just perform a check in the beginning of button_Click:
private void button_Click(object sender, EventArgs e)
{
//two cards are open and not matching (if they matched, they would be already null)
if ( firstClicked != null && secondClicked != null )
{
//hide the buttons
firstClicked.ForeColor = firstClicked.BackColor;
secondClicked.ForeColor = secondClicked.BackColor;
firstClicked = null;
secondClicked = null;
}
}
And delete the timer1.Start() from the end of the event handler.
im not good at understanding other people code, but as far as i look through, you do this in here:
private void button_Click(object sender, EventArgs e)
Check for null
get reference of button 1 and return
get reference of button 2
do win() method
check for equality
here you should send step 5 to front line, check for null as MZetko said, and then check for equality, so it will be third click, else if you get reference as you did, after second button filled up, the checking will also launch
i hope i were helpful
I have created a code for my combobox, that can search addresses in a very large table on Sql Server with the help of stored procedure (i'm working with Entity framework). My stored procedure returns 10 hits and my code fills the combobox with search results. For doing this I'm using BackgroundWorker.
But here I'm now having big problems:
- although the combobox is filled with my search results, it always has the first item selected. Even if I type in only a letter, the whole text gets selected;
After that searching for the address doesn't work anymore. It searches only among these 10 results and I'm having no idea how to solve this. Here is my whole code, that causes me problems:
public String searchedItem = "";
public delegate void DelegateUpdateComboboxSelection(ComboBox myCombo,string value,int count);
BackgroundWorker m_bgworker = new BackgroundWorker();
static AutoResetEvent resetWorker = new AutoResetEvent(false);
m_bgworker.WorkerSupportsCancellation = true;
m_bgworker.DoWork += new DoWorkEventHandler(FillComboboxBindingList);
m_bgworker.RunWorkerCompleted += new RunWorkerCompletedEventHandler(m_bgworker_RunWorkerCompleted);
BindingList<spIskalnikNaslovi_Result1> m_addresses = new BindingList<SP_Result1>();
void m_bgworker_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
{
int count = (int)((object[])e.Result)[0];
string value = (string)((object[])e.Result)[1];
ComboBox myCombo = (ComboBox)((object[])e.Result)[2];
DelegateUpdateComboboxSelection ndelegate = new DelegateUpdateComboboxSelection(UpdateComboSelection);
if (this.InvokeRequired)
{
Invoke(ndelegate, new object[] {myCombo, value, count});
return;
}
else
{
UpdateComboSelection(myCombo, value, count);
return;
}

myCombo.SelectionStart = value.Length;
}
}

{
resetWorker.Set();
e.Cancel = true;
return;
}
else
{
string value = (String)((Object[])e.Argument)[0];
List<SP_Result1> result;
result = _vsebina.SP_searcher(value).ToList<SP_Result1>();
m_addresses = new BindingList<SP_Result1>();
foreach (SP_Result1 rez in result)
{
if (m_addresses.Contains(rez))
{
continue;
}
else
{
m_addresses.Add(rez);
}
}
foreach (SP_Result1 r in m_addresses.ToArray())
{
if (!result.Contains(r))
{
m_addresses.Remove(r);
}
}
e.Result = new object[] { rezultat.Count, vrednost, null };
return;
}
}
private void comboBox9_KeyUp(object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.Back)
{
int searchStart = comboBox9.SelectionStart;
if (searchStart > 0)
{
searchStart--;
if (searchStart == 0)
{
comboBox9.Text = "";
}
else
{
comboBox9.Text = comboBox9.Text.Substring(0, searchStart + 1);
}
}
else
{
searchStart = 0;
}
e.Handled = true;
}
}
private void comboBox9_Enter(object sender, EventArgs e)
{
comboBox9.SelectionStart = 0;
comboBox9.SelectionLength = 0;
}
private void comboBox9_Click(object sender, EventArgs e)
{
comboBox9.Text = "";
}
private void comboBox9_KeyPress(object sender, KeyPressEventArgs e)
{
Search();
}
public void Search()
{
if (comboBox9.Text.Length < 4)
{
return;
}
else
{
if (m_bgworker.IsBusy)
{
m_bgworker.CancelAsync();
m_bgworker = new BackgroundWorker();
m_bgworker.WorkerSupportsCancellation = true;
m_bgworker.DoWork += new DoWorkEventHandler(FillComboboxBindingList);
m_bgworker.RunWorkerCompleted += new RunWorkerCompletedEventHandler(m_bgworker_RunWorkerCompleted);
}
m_bgworker.RunWorkerAsync(new object[] { comboBox9.Text, comboBox9 });
}
}
Maybe can someone enlighten me, what I'm doing wrong. This is first time, that I'm using BackgroundWorker. I have no idea, how
to achieve "search as you type" with combobox in any other way, because my datatable with addresses is quite large (million records).
Thanks in advance for any kind of help or code example.

Edit 1:
Ok, here is my code, before I have used BackGroundWorker. It worked, but it searches very very slow (it can take up to 10 seconds):
private void comboBox9_TextChanged(object sender, EventArgs e)
{
if (comboBox9.Text.Length < 4)
{
return;
}
else
{
FillCombobox(comboBox9.Text, comboBox9);
}
}
public void FillCombobox(string value, ComboBox myCombo)
{
List<spIskalnikNaslovi_Result1> result;
result = _vsebina.spIskalnikNaslovi1(value).ToList();
if (result.Count() > 0)
{
myCombo.DataSource = result;
myCombo.ValueMember = "HS_MID";
myCombo.DisplayMember = "NASLOV1";
var searchedItem = myCombo.Items[0].ToString();
myCombo.SelectionStart = value.Length;
myCombo.SelectionLength = searchedItem.Length - value.Length;
myCombo.DroppedDown = true;
}
else
{
myCombo.DroppedDown = false;
myCombo.SelectionStart = value.Length;
}
return;
}
Is there a way to speed this up without having backgroundworker?
make a button you will call searchbutton
and in click_event of this button call your search() method that run your backgroundworker
that fill the combobox
clear you key_press event of your combobox and it will work
the mistake is you key_press event that call every key stroke happening your search method
so retrieve it
You should get your items in a list, use that list to populate your combobox.
then set AutoCompleteMode property value to Suggest or Append or SuggestAppend and set AutoCompleteSoucre property value to ListItems.
For "Search as you Type", which is actually "Filter as you Type" more than search, you need to implement the OnKeyDown or KeyPressed event.
What you would do is take the search string, which is the current text at the time of the event, then filter the master list using that string. Normally one would use "Starts With" for the filtering, but you could also simply use "Contains". Then you live update the contents of the box with the results from the filter. This is accomplished by changing and refreshing the Datasource.
Here is my final solution without BackGroundWorker. It works quick with my large table, and is upgraded for using a stored procedure on SQL Server (if you use Entity Framework). I use Timer to make sure the user can find a value, that he is searching.
Here you can see the original solution, that I found on this site (thanks to Max Lambertini and algreat for the idea and working concept):
C# winforms combobox dynamic autocomplete
