I have a class called "AddChips" it's basically Prompt Dialog with some buttons and a TextBox the user enter's some data in it and i want to get the data that he just entered and send it back to some other class let's say "Form1" and give the data to integer called Chips
public static string ShowDialog(string text, string caption)
{
Form prompt = new Form();
prompt.Width = 500;
prompt.Height = 150;
prompt.FormBorderStyle = FormBorderStyle.FixedDialog;
prompt.Text = caption;
prompt.StartPosition = FormStartPosition.CenterScreen;
Label textLabel = new Label() { Left = 50, Top = 20, Text = text };
TextBox textBox = new TextBox() { Left = 50, Top = 50, Width = 400 };
Button confirmation = new Button() { Text = "Ok", Left = 350, Width = 100, Top = 70, DialogResult = DialogResult.OK };
Button leaveApp = new Button() { Text = "No", Left = 250, Width = 100, Top = 70, DialogResult = DialogResult.OK };
confirmation.Click += (sender, e) => { new Form1() { Chips = int.Parse(textBox.Text) }; };
leaveApp.Click += (sender, e) => { Application.Exit(); };
prompt.Controls.Add(textBox);
prompt.Controls.Add(confirmation);
prompt.Controls.Add(leaveApp);
prompt.Controls.Add(textLabel);
textLabel.Width = 300;
prompt.AcceptButton = confirmation;
return prompt.ShowDialog() == DialogResult.OK ? textBox.Text : "";
}
I have used on prompt form Like this:
public string ValueIWant { get; set; }
private void btnSetValueIWant_Click(object sender, EventArgs e)
{
if (!string.IsNullOrEmpty(txtbxValue.Text))
{
ValueIWant= txtbxValue.Text;
this.DialogResult = System.Windows.Forms.DialogResult.OK;
Close();
}
}
and on the other form i get Value:
frmValue f= new frmValue ();
if (f.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
string ValueIWantFromProptForm=f.ValueIWant ;
}
It Works for me.

I try to build an application using WinForms and I need something like a JDialog frame to insert several TextBoxes in it (JTextField in Java) along with two buttons (OK and Cancel), but I haven't found yet any appropriate Windows form. Any suggestion?
There is no prompt dialog box in C#. You can create a custom prompt box to do this instead.
public static class Prompt
{
public static int ShowDialog(string text, string caption)
{
Form prompt = new Form();
prompt.Width = 500;
prompt.Height = 100;
prompt.Text = caption;
Label textLabel = new Label() { Left = 50, Top=20, Text=text };
NumericUpDown inputBox = new NumericUpDown () { Left = 50, Top=50, Width=400 };
Button confirmation = new Button() { Text = "Ok", Left=350, Width=100, Top=70 };
confirmation.Click += (sender, e) => { prompt.Close(); };
prompt.Controls.Add(confirmation);
prompt.Controls.Add(textLabel);
prompt.Controls.Add(inputBox);
prompt.ShowDialog();
return (int)inputBox.Value;
}
}
Then call it using:
int promptValue = Prompt.ShowDialog("Test", "123");
I got this from here
Or use this:
using( MyDialog dialog = new MyDialog() )
{
DialogResult result = dialog.ShowDialog();
switch (result)
{
// put in how you want the various results to be handled
// if ok, then something like var x = dialog.MyX;
}
}
So for this assignment in class I'm making a richtextbox editor in C# winforms, in this assignment I have to include a find function, but I can't seem to get the hang of it
EDIT: it closes every time I click the search button, but that's not what I want, I want it to close when the user closes the actual dialog via the X in the top right, the search button should just highlight the found string by using the .Find() method
Here's my code up until now:
private void zoekenToolStripMenuItem_Click(object sender, EventArgs e)
{
string searchValue = SearchDialog();
Search(searchValue);
}
public string SearchDialog()
{
Form findDialog = new Form();
findDialog.Width = 500;
findDialog.Height = 142;
findDialog.Text = "Zoeken";
Label textLabel = new Label() { Left = 10, Top = 20, Text = "Zoek naar:", Width = 100 };
TextBox inputBox = new TextBox() { Left = 150, Top = 20, Width = 300};
Button search = new Button() { Text = "Zoek", Left = 350, Width = 100, Top = 70 };
search.Click += (object sender, EventArgs e) => { findDialog.Close(); };
findDialog.Controls.Add(search);
findDialog.Controls.Add(textLabel);
findDialog.Controls.Add(inputBox);
findDialog.ShowDialog();
return (string)inputBox.Text;
}
void Search(string searchValue)
{
rtxtInhoud.Find(searchValue);
}
The part:
search.Click += (object sender, EventArgs e) => { findDialog.Close(); };
is what I'm really stuck on
Thanks in advance
EDIT: here's something that I tried to do, which didn't work
public string SearchDialog()
{
Form findDialog = new Form();
findDialog.Width = 500;
findDialog.Height = 142;
findDialog.Text = "Zoeken";
Label textLabel = new Label() { Left = 10, Top = 20, Text = "Zoek naar:", Width = 100 };
TextBox inputBox = new TextBox() { Left = 150, Top = 20, Width = 300};
Button search = new Button() { Text = "Zoek", Left = 350, Width = 100, Top = 70 };
Button findNext = new Button() { Text = "Volgende", Left 250, Width = 100, Top = 70};
search.Click += (object sender, EventArgs e) => { rtxtInhoud.Find(inputBox.Text); };
findDialog.Controls.Add(search);
findDialog.Controls.Add(textLabel);
findDialog.Controls.Add(inputBox);
findDialog.ShowDialog();
return (string)inputBox.Text;
}
This waits for the Dialog to be closed before highlighting the found string. Which is NOT what I want, I want it to keep the Dialog open, but still highlight the text
it closes every time I click the search button
Yes, that's because you added an event handler to the search button that closes the form:
search.Click += (object sender, EventArgs e) => { findDialog.Close(); };
but that's not what I want, I want it to [...]
Then write the code in that handler such that it does what you actually want it to do, instead of having it close the form.
In your main form code, create a method that searches your text and highlights a found string. Then hook this method up to your search dialog button like the sample below. Also, I think you should call form.Show() instead of .ShowDialog(), so the other form can respond to input.
private void HighlightString(string stringToHighlight)
{
// Code here to search your text and highlight a string.
}
private void SearchDialog()
{
var findDialog = new Form {Width = 500, Height = 142, Text = "Zoeken"};
var textLabel = new Label() {Left = 10, Top = 20, Text = "Zoek naar:", Width = 100};
var inputBox = new TextBox() {Left = 150, Top = 20, Width = 300};
var search = new Button() {Text = "Zoek", Left = 350, Width = 100, Top = 70};
search.Click += (object sender, EventArgs e) => HighlightString(inputBox.Text);
findDialog.Controls.Add(search);
findDialog.Controls.Add(textLabel);
findDialog.Controls.Add(inputBox);
findDialog.Show();
}
Use this code:
Application.Exit();
I have created a custimazibale prompt
public static class Prompt
{
public static string ShowDialog(int columnnumber, string columnname)
{
Form prompt = new Form();
prompt.Width = 500;
prompt.Height = 150;
prompt.FormBorderStyle = FormBorderStyle.FixedDialog;
prompt.Text = columnname;
prompt.StartPosition = FormStartPosition.CenterScreen;
Label textLabel = new Label() { Left = 50, Top = 20 };
ComboBox comboBox = new ComboBox() { Left = 50, Top = 50, Width = 400 };
comboBox.Items.AddRange(new string[] { "a","b","c" });
comboBox.DropDownStyle = ComboBoxStyle.DropDownList;
comboBox.SelectedItem = columnname;
Button confirmation = new Button() { Text = "Ok", Left = 350, Width = 100, Top = 80 };
confirmation.Click += (sender, e) => { prompt.Close(); };
textLabel.Text = "Colonne " + (columnnumber + 1).ToString() + " : " + columnname;
prompt.Controls.Add(comboBox);
prompt.Controls.Add(confirmation);
prompt.Controls.Add(textLabel);
prompt.AcceptButton = confirmation;
prompt.ShowDialog();
prompt.AcceptButton = confirmation;
return comboBox.Text;
}
}
then I call it in my main form when a header is clicked
private void dataGridView1_ColumnHeaderMouseClick(object sender, DataGridViewCellMouseEventArgs e)
{
dt.Columns[e.ColumnIndex].ColumnName = Prompt.ShowDialog(e.ColumnIndex, dataGridView1.Columns[e.ColumnIndex].Name);
}
The problem is my text change even if the button close is clicked.
But I want it to change only when the user click the button "OK".
You could evaluate the DialogResult and return null if it is not OK:
public static class Prompt
{
public static string ShowDialog(int columnnumber, string columnname)
{
using (Form prompt = new Form())
{
// other code
return prompt.DialogResult == DialogResult.OK ? comboBox.Text : null;
}
}
}
and then in your other method:
private void dataGridView1_ColumnHeaderMouseClick(object sender, EventArgs e)
{
var result = Prompt.ShowDialog(e.ColumnIndex,
dataGridView1.Columns[e.ColumnIndex].Name);
if (result != null)
dt.Columns[e.ColumnIndex].ColumnName = result;
}
And inside your prompt you should set the DialogResult accordingly:
confirmation.Click += (sender, e) =>
{
prompt.DialogResult = DialogResult.OK;
prompt.Close();
};
HINT: Instead of result != null you could also use !String.IsNullOrWhiteSpace(result) to only update the column name if something was entered.
I would go for something like this:
using(Form prompt = new Form())
{
//Initialize the components of your form
DialogResult result = prompt.ShowDialog();
if(result == DialogResult.OK)
{
//return whatever it is you want to return
}
}
Inside your form you can set the DialogResult via prompt.DialogResult = DialogResult.OK and some more options (DialogResult.Cancel, DialogResult.Retry etc.)
You can set a bool when it is confirmed, and use that to return null if it wasn't confirmed, like this:
public static string ShowDialog(int columnnumber, string columnname)
{
Form prompt = new Form();
prompt.Width = 500;
prompt.Height = 150;
prompt.FormBorderStyle = FormBorderStyle.FixedDialog;
prompt.Text = columnname;
prompt.StartPosition = FormStartPosition.CenterScreen;
Label textLabel = new Label()
{
Left = 50,
Top = 20
};
ComboBox comboBox = new ComboBox()
{
Left = 50,
Top = 50,
Width = 400
};
comboBox.Items.AddRange(new string[] { "a", "b", "c" });
comboBox.DropDownStyle = ComboBoxStyle.DropDownList;
comboBox.SelectedItem = columnname;
Button confirmation = new Button()
{
Text = "Ok",
Left = 350,
Width = 100,
Top = 80
};
bool confirmed = false;
confirmation.Click += (sender, e) =>
{
prompt.Close();
confirmed = true;
};
textLabel.Text = "Colonne " + (columnnumber + 1).ToString() + " : " + columnname;
prompt.Controls.Add(comboBox);
prompt.Controls.Add(confirmation);
prompt.Controls.Add(textLabel);
prompt.AcceptButton = confirmation;
prompt.ShowDialog();
prompt.AcceptButton = confirmation;
return confirmed ? comboBox.Text : null;
}
Your calling code will need to check the return value for null, and only do something if the returned value is not null.
public int dialog()
{
Form prompt = new Form(); // creates form
//dimensions
prompt.Width = 300;
prompt.Height = 125;
prompt.Text = "Adding Rows"; // title
Label amountLabel = new Label() { Left = 50, Top = 0, Text = "Enter a number from 1-50" }; // label for prompt
amountLabel.Font = new Font("Microsoft Sans Serif", 9.75F);
TextBox value = new TextBox() { Left = 50, Top = 25, Width = prompt.Width / 2 }; // text box for prompt
Button confirmation = new Button() { Text = "Ok", Left = prompt.Width / 2 - 50, Width = 50, Top = 50 }; // ok button
confirmation.Click += (sender, e) => { prompt.Close(); }; // if clicked it will close
prompt.AcceptButton = confirmation; // enter
prompt.KeyPreview = true;
prompt.KeyDown += (sender, e) =>
{
if (e.KeyCode == Keys.Escape) prompt.DialogResult = DialogResult.Cancel; // user presses ESC key to close
};
// adding the controls
prompt.Controls.Add(value);
prompt.Controls.Add(confirmation);
prompt.Controls.Add(amountLabel);
prompt.ShowDialog();
// returning and checking if int block
int num;
Int32.TryParse(value.Text, out num);
return num;
}
This is the full code. The short version of the code is:
Label amountLabel = new Label() { Left = 50, Top = 0, Text = "Enter a number from 1-50" };
prompt.Controls.Add(amountLabel);
The problem is that it will only display up to "Enter a number". It won't display the full text for some reason. I tried shorter "E" and it worked. I even tried "Enter a number from" but it still didn't fully display.
You could enable AutoSize, which is set to true by default if you create it via the designer:
Label amountLabel
= new Label { AutoSize = true, Left = 50, Top = 0, Text = "Enter a number from 1-50" };
Set the width of the label:
Label amountLabel = new Label() { Left = 75, Top = 0, Width = 1000, Text = "Enter a number from 1-50" };
Don't make the width that wide, though. I just wanted to make sure the text fits without testing different values.
I was surprised that it didn't adjust the width automatically.
Set the Label's AutoSize property to true.
Label amountLabel = new Label() { AutoSize=true, Left = 50, Top = 0, Text = "Enter a number from 1-50" };
I want to create a custom dialog box for my C# project. I want to have a DataGridView in this custom dialog box, and there will also be a button. When the user clicks this button, an integer value is returned to the caller, and the dialog box then terminates itself.
How can I achieve this?
There is no prompt dialog box in C#. You can create a custom prompt box to do this instead.
public static class Prompt
{
public static int ShowDialog(string text, string caption)
{
Form prompt = new Form();
prompt.Width = 500;
prompt.Height = 100;
prompt.Text = caption;
Label textLabel = new Label() { Left = 50, Top=20, Text=text };
NumericUpDown inputBox = new NumericUpDown () { Left = 50, Top=50, Width=400 };
Button confirmation = new Button() { Text = "Ok", Left=350, Width=100, Top=70 };
confirmation.Click += (sender, e) => { prompt.Close(); };
prompt.Controls.Add(confirmation);
prompt.Controls.Add(textLabel);
prompt.Controls.Add(inputBox);
prompt.ShowDialog();
return (int)inputBox.Value;
}
}
Then call it using:
int promptValue = Prompt.ShowDialog("Test", "123");
On your button set the DialogResult property to DialogResult.OK
On your dialog set the AcceptButton property to your button
Create a public property in your form called Result of int type
Set the value of this property in the click event of your button
Call your dialog in this way
using(myDialog dlg = new myDialog())
{
if(dlg.ShowDialog() == DialogResult.OK)
{
int result = dlg.Result;
// whatever you need to do with result
}
}
public static DialogResult InputBox(string title, string promptText, ref string value,bool isDigit=false)
