[Solved] EmptyMessage for GridDropDownColumn

[Mehdi Mirza]

hello,

Is there a possibility for "GridDropDownColumn" have an "EmptyMessage" just like RadComboBox?
I know we can use EnableEmptyListItem="true" EmptyListItemText="Select Model" property. But then the empty value shows in the dropdown which i dont want.
I want it to dissapear just like RadComboBox and not show up in the selection.


thanks

MM

Hello Mehdi,

You can set the EmptyText using the column editor:

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
{
    if (e.Item is GridEditableItem && e.Item.IsInEditMode)
    {
        GridEditableItem item = e.Item as GridEditableItem;
        GridDropDownListColumnEditor editor = item.EditManager.GetColumnEditor("ddc1") as GridDropDownListColumnEditor;
        editor.ComboBoxControl.EmptyMessage = "No text";
    }
}

hello,

this didnt work for me, here is my code

 

 

If (TypeOf e.Item Is GridEditableItem AndAlso e.Item.IsInEditMode) Then

 

 

 

 

Dim item As GridEditableItem = CType(e.Item, GridEditableItem)

 

Dim editor As GridDropDownListColumnEditor = CType(item.EditManager.GetColumnEditor("ModelID"), GridDropDownListColumnEditor)
editor.ComboBoxControl.EmptyMessage = "Select Model"

 

Dim editor1 As GridDropDownListColumnEditor = CType(item.EditManager.GetColumnEditor("SalesAccountType"), GridDropDownListColumnEditor)
editor1.ComboBoxControl.EmptyMessage = "Select Account Type"

 

 

 

 

 

End If

Hello Mehdi,

You can try setting the AllowCustomText property of the control together with the EmptyMessage as shown below. This should probably solve your issue.
vb:

Protected Sub RadGrid1_ItemDataBound(sender As Object, e As GridItemEventArgs)
    If TypeOf e.Item Is GridEditableItem AndAlso e.Item.IsInEditMode Then
        Dim item As GridEditableItem = TryCast(e.Item, GridEditableItem)
        Dim editor As GridDropDownListColumnEditor = TryCast(item.EditManager.GetColumnEditor("DropDownColumn"), GridDropDownListColumnEditor)
        editor.ComboBoxControl.AllowCustomText = True
        editor.ComboBoxControl.EmptyMessage = "No text"
    End If
End Sub

Thanks
Princy.
