For C# winforms.
I wanted to check for each cells in a RadGridView. Wanted to add a eventhandler, once all data dataloaded.
For the cell with value "Completed" I would like to change the cell into a button, lets say a radButton named "radButtonView".

Anyone have any idea how to do that?
A simple example will do :)

Hello Jacky,

Thank you for writing.

If I understand your requirement correctly, you are trying to display a RadButton inside a cell under some circumstances. For this purpose it is suitable to use a GridViewCommandColumn which cells have button by default. Afterwards, you can use the CellFormatting event and hide the button according to your custom conditions.
public Form1()
{
    InitializeComponent();
    for (int i = 0; i < 10; i++)
    {
        this.radGridView1.Rows.Add(i, DateTime.Now.AddDays(i), "Row" + i);
        if (i % 2 == 0)
        {
            this.radGridView1.Rows.Last().Tag = "Completed";
        }
    }
    this.radGridView1.MasterTemplate.Refresh();
}
 
private void radGridView1_CellFormatting(object sender, Telerik.WinControls.UI.CellFormattingEventArgs e)
{
    GridCommandCellElement commandCell = e.CellElement as GridCommandCellElement;
    if (commandCell != null)
    {
        if (e.Row.Tag == "Completed")
        {
            commandCell.CommandButton.Visibility = Telerik.WinControls.ElementVisibility.Visible;
        }
        else
        {
            commandCell.CommandButton.Visibility = Telerik.WinControls.ElementVisibility.Hidden;
        }
    }
}

If it is not the exact requirement please specify in details what is the expected design.

I hope this information helps. Should you have further questions, I would be glad to help.

Hi Desislava,

Thanks for the sample resolution.
The issue is quite urgent and it is resolved by adding expression to the column.
Still glad to try out the sample given by you. Thanks :)

Kind regards,
Jacky
