Edit won't show when using GroupsDefaultExpanded

[Steven]

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">

Thanks alot for the sample.
Where does the "group" var come from?

[Daniel]

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("_"));
}

Hello;

I cannot seem to get this example to function do you have a full code set page and code behind, prefferably vb.

Hi Mike,

Here is the code in VB:

Private group As String = String.Empty
Protected Sub RadGrid1_PreRender(ByVal sender As Object, ByVal 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 Object, ByVal 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"  >

            <MasterTableView   EditMode="inPlace"  GroupsDefaultExpanded="false"    DataSourceID="SqlDataSource1" >
           <GroupByExpressions>
                      <telerik:GridGroupByExpression>
                       <GroupByFields>
                        <telerik:GridGroupByField  FieldAlias="SupplierID" FieldName="SupplierID" />
                       </GroupByFields>
                       <SelectFields>
                       <telerik:GridGroupByField  FieldAlias="SupplierID" FieldName="SupplierID" />
                       </SelectFields>
                      </telerik:GridGroupByExpression>
                    </GroupByExpressions>

             <Columns>

           <telerik:GridBoundColumn DataField="ProductName" UniqueName="ProductName"></telerik:GridBoundColumn>
          <telerik:GridBoundColumn DataField="SupplierID" UniqueName="SupplierID"></telerik:GridBoundColumn>
            <telerik:GridEditCommandColumn></telerik:GridEditCommandColumn>

             </Columns>
           </MasterTableView>

         </telerik:RadGrid>


        </div>
    </form>
</body>
</html>

Thanks

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,

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...
