Change Field Size in RadGrid EditTemplate Form

[Alex]

I have attached a screen shot of my "Edit" Form that opens when I click on Edit from the RadGrid. I am trying to find out how you change the display/edit size of certian fields within the "Edit" Form.

For example the field "CorrectiveAction:" is a large "NText" field and I would like to increase the display/edit field in the Edit Form to show more of the field and even make it a scrollable field so you could see all the text in the field.

Another example is in the field "Status:" I would like to make it a dropdown list and not a free form list to all a user to pick an item and not free form the text.

Any help would be appriciated.

Thx,
Alex.

Hi Alex,
You can set the TextBox width or height by accessing it in the serverside in the ItemDataBound event as shown below. For your next requirement, you can use a GridDropDownColumn or a DropDownList in GridTemplateColumn. For more details take a look at this article on Column Types.

C#:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
 //Accessing Edit Form
  if (e.Item is GridEditableItem && e.Item.IsInEditMode)
  {
    GridEditableItem editItem = (GridEditableItem)e.Item;
    // Access textbox using column UniqueName
    TextBox txtAction = (TextBox)editItem["CorrectiveAction"].Controls[0];
    txtAction.TextMode = TextBoxMode.MultiLine;
  }
}

Thanks,
Princy

I got the Code Converted, but it is not liking the "GridEdittableItem" - am I missing an import or something in my code? It also does not like the "GridItemEventArgs" in the definition of the Sub.


Protected Sub RadGrid1_ItemDataBound(sender As Object, e As GridItemEventArgs)
'Accessing Edit Form
If TypeOf e.Item Is GridEditableItem AndAlso e.Item.IsInEditMode Then
Dim editItem As GridEditableItem = DirectCast(e.Item, GridEditableItem)
' Access textbox using column UniqueName
Dim txtAction As TextBox = DirectCast(editItem("CorrectiveAction").Controls(0), TextBox)
txtAction.TextMode = TextBoxMode.MultiLine
End If
End Sub

Got that fixed - but the field is not changing in the edit mode to "Multiline"..

Ideas why?

Alex.

Hi Alex,

Please add the following ItemDataBound event code snippet:

VB:

Protected Sub RadGrid1_ItemDataBound(sender As Object, e As Telerik.Web.UI.GridItemEventArgs) Handles RadGrid1.ItemDataBound
       If TypeOf e.Item Is GridEditableItem AndAlso e.Item.IsInEditMode Then
           Dim editItem As GridEditableItem = DirectCast(e.Item, GridEditableItem)
           Dim txtAction As TextBox = DirectCast(editItem("ColumnUniqueName").Controls(0), TextBox)
           txtAction.TextMode = TextBoxMode.MultiLine
       End If
   End Sub

Thanks,
Princy
