Hi.
I got this error when i tried to edit the row in a hierarchical grid. I have one nested grid where i changed the UnitPrice value in ItemDataBound event. I need do divide the value to get the right currency. (If i do not, than i can do edit action in the nested grid without getting the error.) I have found in the forum other thread with the same error but it does not solve my case. The code i use is:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)

       {

           if (e.Item is GridDataItem)

           {

               LoadTransAndDetailValues(e);

           }           


       }

 

private void LoadTransAndDetailValues(GridItemEventArgs e)

       {

           var item = e.Item as GridDataItem;

           if (e.Item.DataItem is Detail)

           {               

               var detail = e.Item.DataItem as Detail;                           


               double? unitPrice = detail.UnitPrice;

               item["UnitPrice"].Text = (unitPrice.HasValue && unitPrice.Value != 0) ?    (unitPrice.Value / 100.00).ToString() : "";

           }          


       }

I really need to find out of this error. Anyone??

Hello Cecilie Nordbø,

Note that when an item is in edit mode it renders editor controls instead of text for the its columns. Therefore, you should set your custom value to the relevant column editor. Attached to this message is a small sample that demonstrates how to achieve the desired functionality. Please review it and let me know whether further assistance is needed.

Kind regards,
Martin
