[Solved] Hiding Collaps/Expand icon when no sub-items

[egoren]

Hi,
I've got a few questions related to the expand/collaps column:
1. Is there a way to hide the expand/collaps columns when there are no sub-items for a row
2. is there a way to hide the expand/collaps column itself if none of the rows has sub-items
3. I would like to add a collaps All rows/Expand All rows button

Thanks in advance, Eyal.

Hello Eyal,

You can go through the following help document, to hide the expand/collapse images when there are no records under the parent grid item:
Hiding expand/collapse images when no records

You can add the ExpandAll and CollaoseAll to the CommandItemTemplate and try the following code:
aspx:

<CommandItemTemplate>
      <asp:LinkButton ID="btnExpandAll" CommandName="ExpandAll"  runat="server">ExpandAll</asp:LinkButton>
      <asp:LinkButton ID="btnCollapseAll" CommandName="CollapseAll"  runat="server">CollapseAll</asp:LinkButton>
</CommandItemTemplate>

c#:

protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)
    {
        if (e.CommandName == "ExpandAll")
        {
            foreach (GridDataItem item in RadGrid1.MasterTableView.Items)
            {
                if (!item.Expanded)
                    item.Expanded = true;
            }
        }

        if (e.CommandName == "CollapseAll")
        {
            foreach (GridDataItem item in RadGrid1.MasterTableView.Items)
            {
                if (item.Expanded)
                    item.Expanded = false;
            }
        }
    }

Thanks
Princy.

Thank you Princy for the quick response.
Your answers were both right on the money and we have integrated them into our application. I have found two issues with the 'Hiding expand/collapse images when no records' article and I have notified Telerik about them so hopefully it will be updated soon. Thanks again, Eyal.
