[Manohar]

Hi Team,

I have an issue in  RadDataGrid.

I need to set  cmbbox.DroppedDown =true for a windows combobox on it's foucs but I coudn't. 

I can achieve it when the combobox is out of the RadGrid.

Please help me out with a technique. Thanks in advance.

Hello Manohar,

Thank you for writing.

If I understand correctly, you want to show the popup of a cell in GridViewComboBoxColumn in RadGridView. If so, you need to first call the BeginEdit method of the desired cell, and then handle the CellEditorInitialized event, where you can open the popup:

void radGridView1_CellEditorInitialized(object sender, GridViewCellEventArgs e)
{
    RadDropDownListEditor editor = e.ActiveEditor as RadDropDownListEditor;
    if (editor != null)
    {
        ((RadDropDownListEditorElement)editor.EditorElement).ShowPopup();
    }
}


void radButton1_Click(object sender, EventArgs e)
{
    radGridView1.Rows[2].Cells["combo"].BeginEdit();
}

More information about the editors in the grid is available here: http://www.telerik.com/help/winforms/gridview-editors.html.

I hope this helps. 
 
All the best,
