Hi Mostafa,

Please use this code:

private void dgview_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
{
dgview.EditingControl.KeyPress += new KeyPressEventHandler(dgviewKeyPress);
}

private void dgviewKeyPress(object sender, KeyPressEventArgs args)
{
if (!char.IsDigit(args.KeyChar))
args.Handled = true;
}

Please let me know if this helps.

Thanks,

Gopal.S

Use DataGrid.EndEdit method to validate if the entered value is numeric or not. Have a look at MSDN Library DataGrid.EndEdit where you can find an example code. Hope this helps.

Hi Mustafa,

Here is the another solution:

namespace Sample
{
public partial class Form1 : Form
{
DataGrid dGird;
public Form1()
{
InitializeComponent();
}

private void Form1_Load(object sender, EventArgs e)
{

dGird = new DataGrid();
dGird.CurrentCellChanged += new EventHandler(dGridCellChanged);

DataTable dt = new DataTable();
dt.Columns.Add("SNo");
dt.Columns.Add("Name");
dt.Columns.Add("Amount");
dt.Columns.Add("Address");
DataRow drow = dt.NewRow();
drow[0] = "01";
drow[1] = "Gopal";
drow[2] = "100";
drow[3] = "TTL";
dt.Rows.Add(drow);
drow = dt.NewRow();
drow[0] = "02";
drow[1] = "Raja";
drow[2] = "150";
drow[3] = "SSS";
dt.Rows.Add(drow);
dGird.DataSource = dt;
dGird.Size = new Size(400, 400);
this.Controls.Add(dGird);

System.Windows.Forms.Control.ControlCollection ctlCollection = dGird.Controls;
if (dGird.CurrentCell.ColumnNumber == 0)
ctlCollection[2].KeyPress += new KeyPressEventHandler(dgKeyPress);
}

private void dgKeyPress(object sender, KeyPressEventArgs args)
{
if (!char.IsDigit(args.KeyChar) && args.KeyChar!=(char)Keys.Back)
args.Handled = true;
}

private void dGridCellChanged(object sender, EventArgs args)
{
// Control index - 0,1 assigned for scrollbars(default).

System.Windows.Forms.Control.ControlCollection ctlCollection = dGird.Controls;
if (dGird.CurrentCell.ColumnNumber == 0)
ctlCollection[2].KeyPress += new KeyPressEventHandler(dgKeyPress);
else if (dGird.CurrentCell.ColumnNumber == 2)
ctlCollection[4].KeyPress += new KeyPressEventHandler(dgKeyPress);

}

}
}

please let me know if this helps.

Thanks,

Dear all,

Thank you for replying to my earlier post ; it was extremely helpfull. However, I've got another question. I use the following code :

private void treeView1_Click(object sender, System.EventArgs e)<br />
        {<br />
            TreeNode node = treeView1.SelectedNode;<br />
            lblResName.Text = node.ToString();<br />
        }

This produces the following output to the text property of the label :

Treenode:text

Is there a way to show only the content of the row in the treenode, without the Treenode: prefix attached to it.

Cheers Smile | :)

Fixed it ...

instead of using :

lblResName.Text = node.ToString();

I tried :

lblResName.Text = node.Text.ToString();

and that worked !

DLL file

abedo19826-May-07 9:07

can i program an application to generate dll file as an output ,for example:

program generate the following code :

class cars
{
private string _Model;
Private string _Type;

public Cars()
{

}

public string Model
{
get{return _Model;}
set{_Model=Value;}
}

public string Model
{
get{return _Model;}
set{_Model=Value;}

}

I need to convert the above code to a dll(Cars.dll) file that simply can use it:

Please help me to do it,

Yes you can. When creating a new project choose windows class library.
