When using the GroupsDefaultExpanded = False, and also using inline editing, when I click the editbutton, my inline edit form won't show but instead the group collapses again. When using groups and not having GroupsDefaultExpanded on false there is no problem.

Using 2008.3.1124, in a dotNetNuke module. But also tried a testpage without dotnetnuke with the same problem.

Hello Steven,

This is the default behavior of the GroupsDefaultExpanded property when it's set to False. In order to be able to open the InPlace edit mode in this scenario I suggest you set GroupLoadMode to "Client".

Actually, it's possible to implement this functionality in your project. A sample code is shown below:
protected void RadGrid1_PreRender(object sender, EventArgs e) 
    if (!string.IsNullOrEmpty(group)) 
    { 
        GridItem[] items = RadGrid1.MasterTableView.GetItems(GridItemType.GroupHeader); 
        foreach (GridGroupHeaderItem item in items) 
            if (item.GroupIndex == group) 
                item.Expanded = true
    } 
 
protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e) 
    if (e.CommandName == RadGrid.EditCommandName) 
        group = e.Item.GroupIndex.Substring(0, e.Item.GroupIndex.LastIndexOf("_")); 

<MasterTableView AutoGenerateColumns="false" CommandItemDisplay="Top" GroupsDefaultExpanded="false" 
    GroupLoadMode="Client" EditMode="InPlace"

Let us know if you need more information.

Hello Steven,

Actually there is an error in the example (I omit a mandatory check -> RadGrid1.MasterTableView.GroupByExpressions.Count > 0).

Please find the modified version below:
string group = string.Empty; 
 
protected void RadGrid1_PreRender(object sender, EventArgs e) 
    if (!string.IsNullOrEmpty(group)) 
    { 
        GridItem[] items = RadGrid1.MasterTableView.GetItems(GridItemType.GroupHeader); 
        foreach (GridGroupHeaderItem item in items) 
            if (item.GroupIndex == group) 
                item.Expanded = true
    } 
 
protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e) 
    if (e.CommandName == RadGrid.EditCommandName && RadGrid1.MasterTableView.GroupByExpressions.Count > 0) 
        group = e.Item.GroupIndex.Substring(0, e.Item.GroupIndex.LastIndexOf("_"));

Hi Mike,

Here is the code in VB:

Private group As String = String.Empty 
Protected Sub RadGrid1_PreRender(ByVal sender As ObjectByVal e As EventArgs) 
     If Not String.IsNullOrEmpty(group) Then 
        Dim items As GridItem() = RadGrid1.MasterTableView.GetItems(GridItemType.GroupHeader) 
         For Each item As GridGroupHeaderItem In items 
             If item.GroupIndex = group Then 
                 item.Expanded = True 
             End If 
         Next 
     End If 
     
 End Sub 
 Protected Sub RadGrid1_ItemCommand(ByVal source As ObjectByVal e As GridCommandEventArgs) 
     If e.CommandName = RadGrid.EditCommandName AndAlso RadGrid1.MasterTableView.GroupByExpressions.Count > 0 Then 
         group = e.Item.GroupIndex.Substring(0, e.Item.GroupIndex.LastIndexOf("_")) 
    End If 
   End Sub 


ASPX:
 <telerik:RadGrid ID="RadGrid1" runat="server"    DataSourceID="SqlDataSource1" OnPreRender="RadGrid1_PreRender" OnItemCommand="RadGrid1_ItemCommand" GridLines="None"  >

                       <telerik:GridGroupByField  FieldAlias="SupplierID" FieldName="SupplierID" /> 
                       </SelectFields> 
                      </telerik:GridGroupByExpression> 
                    </GroupByExpressions>

I have the same problem with EditMode="EditForms", and the suggested codes work for me.  However, when I have more than one item from the same group that are in the edit mode, updating or canceling the edit for one item will collapse the group.  I would like to keep the group expanded since there are other items in the edit mode.  To accomplish this, I tried to keep tracking which group index should be expanded by doing:

protected void Grid1_ItemCommand(object source, GridCommandEventArgs e)  
{  
    if (e.CommandName == RadGrid.EditCommandName && Grid1.MasterTableView.GroupByExpressions.Count > 0)  
    {  
        AddExpandedGroupIndex(e.Item.GroupIndex.Substring(0, e.Item.GroupIndex.LastIndexOf("_")));  
    }  
    if (e.CommandName == RadGrid.CancelCommandName && Grid1.MasterTableView.GroupByExpressions.Count > 0)  
    {  
        RemoveExpandedGroupIndex(e.Item.GroupIndex.Substring(0, e.Item.GroupIndex.LastIndexOf("_")));  
    }  
 
but then I realized that e.Item.GroupIndex is not available when e.CommandName == RadGrid.CancelCommandName.  Is there any way I can make it work?  Thanks,

Peichung

Hi Shinu

   i'm having this same problem with the Edit but in a detail table. the code does not work for the detail table.
can you explain how the expand collapse function works.

i tried this in the RadGrid_Prerender Sub but it is not working ? i don't understand why...

Dim item As GridItem
      For Each item In RadGrid1.MasterTableView.DetailTables.Item(0).Controls
          If TypeOf item Is GridGroupHeaderItem Then
              If item.IsInEditMode Then
                  item.Expanded = True
              Else
                  item.Expanded = False
              End If
               End If
      Next item


thanks...
