What I have is a search button, which connects to the database, but then when I hit search and the txtEstado TextBox is not empty, it should disable the other txtboxes, but it does so when I query with another search, that is to say in the second click, but I need that when the txtbox is with values these are disabled at once, when pressing the search button

I have spent some time designing my first project using C#, it is a Windows form project with 8 buttons on the side. pressing one of the buttons will open another form within the parent form as a window. On clicking the button the new form loads up about 27 objects mostly Labels, Textboxes, Comboboxes and a few DateTimePickers. For some reason it you can see it drawing the boxes and it looks slow. I have an SQL db included with my project which is tiny and contains only 2 rows of data. It is very dishearting to spend all that time working on it only to see it run like a ZX Spectrum. I am using Microsoft Visual Studio 2019 and is fully updated. I have no errors, no warnings thank god but the performance is horrible. One of the comboBoxes when selected will make visible 3 more textBoxes and even making those visible is really slow. Is there something I am doing wrong or is there a way to have it working faster please?
This is the code of my childForm which opens from the main parentForm, sorry is is a bit long but it is all of it.

I'm setting datagridview as object and show in windows form in Textbox change event. When open form and start texting into textbox then datagridview is show but when text is empty or null datagridview continue been visible. How can I accomplish datagridview invisible in windows form?
This is for C#. I have tried to dispose datagridview in if clause but it didn't work.
Here is my code:
public class CreateDataGridView
{
public DataGridView clientsDgv = new DataGridView();
public CreateDataGridView()
{
clientsDgv.ReadOnly = true;
clientsDgv.Name = "clientsDgv";
clientsDgv.AllowUserToAddRows = false;
clientsDgv.AllowUserToDeleteRows = false;
clientsDgv.AllowUserToResizeRows = false;
}
public DataGridView Createdgv()
{
return clientsDgv;
}
Here is my code in windows form.
//Get datagridview in windows form textbox change event
private void TxtID_TextChanged(object sender, EventArgs e)
{
switch (this.cmbSelectAction.SelectedIndex)
{
case 1:
CreateDataGridView clientsdgv = new CreateDataGridView();
//clientsdgv.clientsDgv
Controls.Add(clientsdgv.clientsDgv);
clientsdgv.clientsDgv.BringToFront();
DesignDataGridView designdgv = new DesignDataGridView();
designdgv.ClientsDataGridFormatting(clientsdgv.clientsDgv);
designdgv.ClientsDataGridPosition(clientsdgv.clientsDgv, txtID);
//SetDoubleBuffered.SetDoubleBuffering(clientsdgv.clientsDgv, true);
if (string.IsNullOrEmpty(txtID.Text) || txtID.Text == "0")
{
clientsdgv.clientsDgv.DataSource = null;
clientsdgv.clientsDgv.Update();
clientsdgv.clientsDgv.Dispose();
clientsdgv.clientsDgv.Visible = false;
return;
}
else
{
GetSqlData getSqlData = new GetSqlData();
try
{
clientsdgv.clientsDgv.SuspendLayout();
columnName = "PersonalIDBulstat";
ID = txtID.Text;
clientsdgv.clientsDgv.Visible = true;
clientsdgv.clientsDgv.DataSource = getSqlData.SearchClientsInSql(columnName, ID);
clientsdgv.clientsDgv.Update();
clientsdgv.clientsDgv.ResumeLayout();
}
catch
{
title = "Clients";
SetMessageBoxTypes.MessageBoxContactAdminOk(title);
}
}
break;
}
}
Thank you in advance!
It is my working code when form is load where dgvClients is declare as DataGridView:
private void Clients_Load(object sender, EventArgs e)
{
CreateDataGridView clientsdgv = new CreateDataGridView();
dgvClients = clientsdgv.dgvClients;
}
private void TxtID_TextChanged(object sender, EventArgs e)
{
switch (this.cmbSelectAction.SelectedIndex)
{
case 1:
Controls.Add(dgvClients);
dgvClients.BringToFront();
DesignDataGridView designdgv = new DesignDataGridView();
designdgv.ClientsDataGridPosition(dgvClients, this.txtID);
GetSqlData getSqlData = new GetSqlData();
if (string.IsNullOrEmpty(txtID.Text) || txtID.Text == "0")
{
dgvClients.DataSource = null;
dgvClients.Update();
dgvClients.Visible = false;
return;
}
else
{
try
{
dgvClients.SuspendLayout();
columnName = "PersonalIDBulstat";
ID = txtID.Text;
dgvClients.Visible = true;
dgvClients.DataSource = getSqlData.SearchClientsInSql(columnName, ID);
dgvClients.Update();
dgvClients.ResumeLayout();
}
catch
{
title = "Clients";
SetMessageBoxTypes.MessageBoxContactAdminOk(title);
}
}
break;

I'm setting a IT project for the school and i got a problem with the datagridview in c# Winform.
I made a first form with a datagridview connected to my db and i want to make a button who can delete a row from the datagridview if needed.
To make sure the client doesn't make a mistake, i create another form where it ask "do you want to delete this row ? (yes/no)", that's a basic form (label + button).
But when i want to close this form, i go to a function in my first datagrid who will initialize this grid from the start of the program and in this code I use Datagridview.DataSource to make a loop.
The problem is marked here, and when I print my DataSource, it print me nothing like there is no DataSource...
Does anyone the reason or how to keep the DataSource from the previous form when you pop's up a new one ?
My code for the initial grid
public void InitDatagrid()
{
//Initialize the tools
CancelMod.Visible = false;
ApplyMod.Visible = false;
Modifie.Visible = true;
Prevbtn.Visible = true;
ClientCommand.Enabled = true;
Client_Pieces.Enabled = true;
Prices.Enabled = true;
PieceCommand.Enabled = true;
Pieces.Enabled = true;
textBox1.Enabled = true;
RowAdd.Visible = false;
RowDelete.Visible = false;
textboxDel.Visible = false;
labelDel.Visible = false;
dataGridView1.EditMode =
DataGridViewEditMode.EditProgrammatically;
textBox1.Text = "";
this.pieceTableAdapter.Fill(this.mykitboxDataSet5.piece);
//Put the color of the columns as white (initial color)
for (var i = 0; i < ((DataTable)dataGridView1.DataSource).Columns.Count; i++)
{
dataGridView1.Columns[i].DefaultCellStyle.BackColor = Color.White;
}
int count = ((DataTable)dataGridView1.DataSource).Columns.Count;
//Put the changed cells color as white (initial color)
if (count == 8)
{
dataGridView2.EditMode =
DataGridViewEditMode.EditProgrammatically;
DeleteCommand.Visible = false;
textBoxDel2.Visible = false;
labelDel2.Visible = false;
for (int i = 0; i < Convert.ToInt32(dataGridView1.Rows.Count.ToString()); i++)
{
//Column = payment_status and command_status
dataGridView1.Rows[i].Cells[6].Style.BackColor = Color.White;
dataGridView1.Rows[i].Cells[7].Style.BackColor = Color.White;
}
}
}
Here is my code for the pop up
public PopUpDel(string codedb, string text, DataGridView ds)
{
this.codedb = codedb;
InitializeComponent();
code.Text = codedb;
label1.Text = text;
Console.WriteLine(ds);
}
private void yes_Click(object sender, EventArgs e)
{
SKGridPage sk = new SKGridPage();
sk.SqlConnection();
MySqlCommand command = conn.CreateCommand();
command.CommandText = string.Format("DELETE FROM piece WHERE code = '{0}'", this.codedb);
Console.WriteLine(command.CommandText);
try
{
conn.Open();
command.ExecuteNonQuery();
}
catch (Exception x)
{
Console.WriteLine(x.Message);
}
conn.Close();
this.Close();
sk.InitDatagrid();
}
private void no_Click(object sender, EventArgs e)
{
this.Close();
}
}
I have the following code that I use to update my datagridview:
public readonly BindingList<InventoryTransaction> InventoryTransactions = new BindingList<InventoryTransaction>() { RaiseListChangedEvents = true };
private bool _scanning;
private string _checkData;
public BarCodeForm()
{
InitializeComponent();
barCodeForm_InventoryTransactionBindingSource.DataSource = InventoryTransactions;
panel1.Enabled = false;
_scanning = true;
timer_ScanTimer.Enabled = false;
//InventoryTransactions.AddingNew += InventoryTransactions_AddingNew;
}
private void timer_ScanTimer_Tick(object sender, EventArgs e)
{
panel1.Enabled = true;
label_Message.Text = "Please press ENTER or click RESET to scan again.";
timer_ScanTimer.Enabled = false;
textBox_ModelNumber.Text = _checkData;
textBox_Quantity.Text = "1";
var qry = (from x in InventoryTransactions
where x.ModelNumber == _checkData
select x).FirstOrDefault();
_checkData = string.Empty;
if (qry == null)
{
textBox_Quantity.Focus();
return;
}
qry.Quantity += qry.Quantity;
barCodeForm_InventoryTransactionBindingSource.EndEdit();
panel1.Enabled = false;
_scanning = true;
timer_ScanTimer.Enabled = false;
panel1.Text = "Scan now!";
ResetForm();
}
The problem is that I have updated the quantity of the InventoryTransactions but my datagridview is not updating. Do I have to issue a command of some sort to force the update or to apply the changes?
Thanks!

Please view image for more clarification of the problem bcz i know i'm not able to make it more clear to you.
I want to update data for only those columns which are checked by user via checkboxes and those which are left unchecked don't get updated by NULL value....
what i'm thinking is use 511 if....else conditions each for different update query but it's not possible to implement this.
till now the code for update is this:
else if(update_rdbtn.Checked)
{
FileStream fstream = new FileStream(this.imglocation_lbl.Text, FileMode.Open, FileAccess.Read);
BinaryReader br = new BinaryReader(fstream);
imgbtarray = br.ReadBytes((int)fstream.Length);
SqlConnection con = new SqlConnection("Data Source=JackSparrow-PC\\sqlexpress;Initial Catalog=HCE_DB;Integrated Security=True;Pooling=False");
SqlCommand cmd = new SqlCommand("Update StudentInfo SET Rollno='" + this.rollno_txtbox.Text + "',Student_Name='" + this.studname_txtbox.Text + "',F_name='" + this.fname_txtbox.Text + "',D_O_B='" + this.dob_txtbox.Text + "',Address='" + this.address_txtbox.Text + "',Phone='" + this.phone_txtbox.Text + "',Valid_upto='" + this.validupto_txtbox.Text + "',Image=#IMG,Branch='" + this.branch_txtbox.Text + "' WHERE Rollno='" + this.rollno_txtbox.Text + "';", con);
SqlDataReader myReader;
try
{
con.Open();
cmd.Parameters.Add(new SqlParameter("#IMG", imgbtarray));
myReader = cmd.ExecuteReader();
MessageBox.Show("Data has been updated");
myReader.Close();
con.Close();
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
