Hello Daniel,

One possible option in this case would be to handle the validation on the server, in whatever event will be used to perform the inser/update operation for the grid. If validation fails, you can cancel out the event, as shown in the following code snippet:

.cs

    
            protected void RadGrid1_UpdateCommand(object source,  
        
                    Telerik.Web.UI.GridCommandEventArgs e)  
        
            {  
        
               GridEditableItem eeditedItem = e.Item as GridEditableItem;  
        
               DataTable ordersTable = this.GridSource;  
        
               //Locate the changed row in the DataSource  
        
               DataRow[] changedRows = ordersTable.Select("OrderID = " +  
        
                         editedItem.OwnerTableView.DataKeyValues[editedItem.ItemIndex]["OrderID"].ToString());  
        
               if (changedRows.Length != 1)  
        
               {  
        
                   this.Label1.Text += "Unable to locate the Order for updating.";  
        
                   e.Canceled = true;  
        
                   return;  
        
               }  
        
               //Update new values  
        
               Hashtable newnewValues = new Hashtable();  
        
               e.Item.OwnerTableView.ExtractValuesFromItem(newValues, editedItem);  
        
               changedRows[0].BeginEdit();  
        
               try  
        
               {  
        
                   foreach (DictionaryEntry entry in newValues)  
        
                   {  
        
                       changedRows[0][(string)entry.Key] = entry.Value;  
        
                   }  
        
                   changedRows[0].EndEdit();  
        
               }  
        
               catch (Exception ex)  
        
               {  
        
                   changedRows[0].CancelEdit();  
        
                   Label1.Text += "Unable to update Orders. Reason: " + ex.Message;  
        
                   e.Canceled = true;  
        
               }  
        
            }

I hope this gets you started properly.

All the best,

I am searching around the forums to a solution to my problem. My problem sounds a bit similar with the validation and clicking the add button. Basically what occurs in my scenario is that I have a drop down and 3 textboxes that are required. I have RequiredValidators for the textboxes and a CustomValidator for the drop down list. When I click to add a new record, my Insert Form displays, I don't enter in any information so my validation will fail (which is what I want), then I click on the Add button, I get my validation messages, I then click on the Add button again, and here is where the problem is....my Insert Form collapses or dissapears? Why? The only thing I can think of is the e.Canceled = true; in the RGRDUserList_ItemCommand event. Here is my code:

ASPX Page:

                       cursor: hand;  
        
                    }  
        
                    .GridDeleteImageButton  
        
                    {  
        
                       cursor: hand;

So basically in the end I am left with a page that if I click the Add button twice in a row, the insert form dissapears...I am confused. Shouldn't the Insert form stay open and continue to display the validation messages? BTW the Telerik Forum Support team is awesome!

Thanks,
