Glossary Item Box

To display the grid column editors inline when switching grid item in edit mode (see the screenshot below), you simply need to change the MasterTableView EditMode property to InPlace.


ASPX/ASCX Copy Code
<rad:RadGrid id="RadGrid1" runat="server">
<MasterTableView AutoGenerateColumns="True" EditMode="InPlace" />
</rad:RadGrid>

A row in edit mode 

Since version 4.0.3 Telerik RadGrid exposes MaxLength property for GridBoundColumn. Setting this property to integer value will limit the number of symbols which can be entered in the default textbox editor (when item is switched in edit mode).


Relations between the edited item and the item in regular mode


When InPlace editing is applied, the grid row is of type GridDataItem in regular mode and  GridEditableItem in edit regime. Hence you can cast the item in the ItemCreated event (for example) to those types according to its current mode:

C# Copy Code
private void RadGrid1_ItemCreated(object sender, Telerik.WebControls.GridItemEventArgs e)
{
  if(e.Item is GridDataItem)
  {
     //the item is in regular mode
     GridDataItem dataItem = e.Item as GridDataItem;
     //do something here
   }
  else if (e.Item is GridEditableItem && e.Item.IsInEditMode)
  {
    //the item is in edit mode
    GridEditableItem editedItem = e.Item as GridEditableItem;
    //do something here
  }
}
VB.NET Copy Code
Private Sub RadGrid1_ItemCreated(ByVal sender As Object, ByVal e As Telerik.WebControls.GridItemEventArgs) Handles RadGrid1.ItemCreated
         If (TypeOf e.Item is GridDataItem) Then

             'the item is in regular mode
             Dim dataItem As GridDataItem = CType(e.Item,GridDataItem)
             'do something here

         ElseIf (TypeOf e.Item is GridEditableItem AndAlso e.Item.IsInEditMode) Then

             'the item is in edit mode
             Dim editedItem As GridEditableItem = CType(e.Item, GridEditableItem)
             'do something here

         End If
End Sub
