Question

I have a gridview in my C# windows application … It allowed to be edited and I want a special cell (named “Price”) to just allow number on keypress … I use the code below for texboxes to just allow numbers … in which event of grid view should I write this code?

     private void txtJustNumber_KeyPress(object sender, KeyPressEventArgs e)
    {
        if (!char.IsDigit((char)(e.KeyChar)) &&
            e.KeyChar != ((char)(Keys.Enter)) &&
            (e.KeyChar != (char)(Keys.Delete) || e.KeyChar == Char.Parse(".")) &&
            e.KeyChar != (char)(Keys.Back))
        {
            e.Handled = true;
        }
    }

thx guys … I used below code and my problem resolved …

    public Form1()
    {
        InitializeComponent();
        MyDataGridViewInitializationMethod();
    }

    private void MyDataGridViewInitializationMethod()
    {
        gvFactorItems.EditingControlShowing +=
            new DataGridViewEditingControlShowingEventHandler(gvFactorItems_EditingControlShowing);
    }

    private void gvFactorItems_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
    {
        e.Control.KeyPress += new KeyPressEventHandler(Control_KeyPress); ;
    }

    private void Control_KeyPress(object sender, KeyPressEventArgs e)
    {

        if (!char.IsDigit((char)(e.KeyChar)) &&
            e.KeyChar != ((char)(Keys.Enter)) &&
            (e.KeyChar != (char)(Keys.Delete) || e.KeyChar == Char.Parse(".")) &&
            e.KeyChar != (char)(Keys.Back))
        {
            e.Handled = true;
        }
    }
