Using RadComboBox in Edit mode in Subgrid

[Stephan]

I have a Grid (SubGrid1) within a Grid (RadGrid1).
When I edit SubGrid1 I need to load values for a RadComboBox.
I'm currently loading values for RadGrid1 without problems through the RadGrid_ItemDataBound event:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
      if ((e.Item is GridEditableItem) && (e.Item.IsInEditMode))
      {
           //Loading RadComboBoxes here without problems
           //...
      }
      //...
}

When I try to do the same for SubGrid1 I came to find out that the SubGrid1_ItemDataBound event is not being called upon selecting "Edit" on this grid.

protected void RadGridPhones_ItemDataBound(object sender, GridItemEventArgs e)
{
     //This event is not firing.
}

Can anybody see anything wrong with how I do it? I don't use DataSourceID, but there has got to be a way to get it to work this way too.

The only difference between RadGrid1 and SubGrid1 is that I do an InPlace edit on SubGrid1.

Thanks.

Hello Stephan,

I suppose that you have placed SubGrid1 in the NestedViewTemplate of RadGrid1. From your aspx code, you have set the Item DataBound event handler as OnItemDataBound="SubGrid1_ItemDataBound" but the event handler is declared as:

protected void RadGridPhones_ItemDataBound(object sender, GridItemEventArgs e)
{

}

As per your aspx declaration, the event handler for SubGrid1 should be actually declared as:

protected void SubGrid1_ItemDataBound(object sender, GridItemEventArgs e)

{

}

Please feel free to correct me, if i'm missing out on something.

Hi Princy,

I pasted the wrong code snippet. It should have read:

protected void SubGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
     //This event is not firing.
}

Thanks for catching that and sorry for the confusion.

My control is fairly big and I meant to only paste the code relevant to this issue.
