Hi Riddhish Chaudhari,

I guess you have a RadcomboBox outside the Grid and you want a control inside editform to be accessed from that RadcomboBox . Please take a look at the following code snippet.

C#:

protected void RadComboBox1_SelectedIndexChanged(object sender, RadComboBoxSelectedIndexChangedEventArgs e)
{
    RadComboBox combo = (RadComboBox)sender;
    string value = combo.SelectedValue;
    //During EditMode
    foreach (GridDataItem item in RadGrid1.EditItems)
    {
        GridEditableItem edititem = (GridEditableItem)item.EditFormItem;
        PlaceHolder placehldr = (PlaceHolder)edititem.FindControl("plupload");
        if (value == "2")
        {
            placehldr.Visible = false;
        }
        else
        {
            placehldr.Visible = true;
        }
    }
    //During InsertMode
    if (RadGrid1.MasterTableView.IsItemInserted)
    {
        GridEditableItem insert = (GridEditableItem)RadGrid1.MasterTableView.GetInsertItem();
        PlaceHolder ph = (PlaceHolder)insert.FindControl("plupload");
        if (value == "2")
        {
            ph.Visible = false;
        }
        else
        {
            ph.Visible = true;
        }
    }
}

Thanks,
Princy

hey Princy, your code working great, but it's only working if i am in edit mode, every time i have to first select combobox item and then i have to go for edit/insert, can you help me to  just select only once in combobox and this functionality working until next PostBack of combobox.
