[Solved] Latest RadGrid Expand collapse no longer works

[VeriFone]

we have our piece of code which worked perfectly for ExpandCollapse command until we upgraded to latest control set:

switch (e.CommandName)

                {

                    case RadGrid.ExpandCollapseCommandName:

                        {

                            gridId = (GridDataItem)e.Item;

                            ViewState["mkAccountID"] = gridId.GetDataKeyValue("mkAccountID").ToString();

                            ViewState["DecimalPlaces"] = gridId.GetDataKeyValue("DecimalPlaces").ToString();

 

                            //Set paramaters for dsAccountTID

                            dsAccountTID.SelectParameters.Clear();

                            dsAccountTID.SelectParameters.Add("mkAccountId", ViewState["mkAccountID"].ToString());

 

                            //Set paramaters for dsAccountCardSchemes

                            dsAccountCardSchemes.SelectParameters.Clear();

                            dsAccountCardSchemes.SelectParameters.Add("mkAccountId", ViewState["mkAccountID"].ToString());

 

                            if (SharedUtilities.ExpandCollapseItems(e.Item))

                                e.Canceled = true;

                        }

                        break;

            

public static bool ExpandCollapseItems(GridItem item)
   {

       try
       {
           // expand the grid data item that has been clicked
           // and collapse any other so that we only ever get
           // one expanded.
           foreach (GridDataItem gdi in item.OwnerTableView.Items)
           {
               if (gdi.ItemIndexHierarchical == item.ItemIndexHierarchical)
               {
                   gdi.Expanded = !gdi.Expanded;
               }
               else
               {
                   gdi.Expanded = false;
               }
           }
           return true;
       }
       catch (Exception ex)
       {
           throw new Exception("ExpandCollapseItems: " + ex);
       }
   }

While debugging everything looks correct apart from the fact that selected DetailTable doesn't expand.
Any thought's ?

Hello Mark,

I have assembled a sample project based on your code which works on my side. You could take a look at the attached page in order to observe if there are any differences at your end. In order to further investigate the problem you could open a formal ticket and attach a modified version of the project which shows the unwanted behavior so we could debug it and advice you with the best possible solution.

All the best,
