Hello there, I'm trying to conditionally hide a row on the server side.  My code looks like this:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)  
{  
    if (e.Item.ItemType == GridItemType.Item || e.Item.ItemType == GridItemType.AlternatingItem)  
    {  
        if (e.Item.OwnerTableView.Name == "Customer")  
        {  
 
        }  
 
        if (e.Item.OwnerTableView.Name == "CustomerDetail")  
        {  
            CustomerDetail detail = (CustomerDetail)e.Item.DataItem;  
            if (detail.IsCancelled)  
            {  
                // Hide the row, e.Item.Visible = false  doesn't seem to work
            }  
        }  
    }  

The good news is the code gets hit during debugging, and at that point, I'd like to hide the row.  The row does reside inside of a DetailTable/GridTableView.  Do I need to do this inside of another server side event?  Or should I filter my results when the detailtable gets databound?

I've searched these forums for quite a while but no luck . Any help is greatly appreciated.

Hello Mike,

Try hiding the row that reside in Detailtable by setting the Display property to false.

if (e.Item.OwnerTableView.Name == "CustomerDetail"
    e.Item.Display = false

Hope this helps,
Shinu

Hi,

There is a bug in the RadGrid where if you hide the row on server side (using e.Item.Display = false or e.Item.Visible = false) and using Grouping functionality of the grid then expand collapse do not work. What's happening is when doing group expand collapse it will NOT hide all the rows. See attached screenshot about the bug.


        protected void radGrid_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e) 
        { 
            switch (e.Item.ItemType) 
            { 
               case Telerik.Web.UI.GridItemType.GroupFooter:  
                    Telerik.Web.UI.GridSplitGroup splitGroup = ((System.Data.DataRowView)e.Item.DataItem)["SplitGroup"as Telerik.Web.UI.GridSplitGroup;  
  
                    if (e.Item.GroupIndex.Contains("_"))  
                    {  
                        e.Item.Display = false;  
                        e.Item.Visible = false;  
                    }  
  
                    break;  
             } 
         }
