HI ,

I am using the Rad grid which is bind dynamically through code from code behind.

1.CRUD operation are performed on UpdateCommand,InsertCommand and DeleteCommand event.

2. I have another event lie need_datasource and itemdatabound event.

4.Paging is true.

When I click on Edit button on first page it works correctly. But when I go to Next or any other page apart from 1 page. it open the wrong record for editing. e.g I click on 2nd record on page 2 than it open the other recrord to edit.

Flow of event.
Click on Edit -> fires Need_Datasource event (which don't have RadGrid.Databind()).-> itemDataBound event is called -> it fetching the wrong datakey here. Below is the code of itemdatabound

if ((e.Item is GridEditableItem || e.Item is GridDataItem) && e.Item.IsInEditMode)
            {
                clsPEstimateLineItem objEstimatelineItem = new clsPEstimateLineItem();
                GridEditableItem editForm = (GridEditableItem)e.Item;
               
                objEstimatelineItem.LineItemId = clsFilter.IntNullFilter(item.GetDataKeyValue("LineItemId").ToString());
                //objEstimatelineItem.LineItemId = clsFilter.IntNullFilter(e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["LineItemId"]);
                DataSet dslineItem = objBEstimateLineItem.GetEstimateLineItemById(objEstimatelineItem);

               RadTextBox txtDescription = editForm.FindControl("txtDescription") as RadTextBox;
                string Description = dslineItem.Tables[0].Rows[0].Field<string>("Description");
                txtDescription.Text = Description.ToString();
       }

Thanks
Ajay
