[Solved] Close all nestedviews in code

[Daniel Pålsson]

Is there any way to close all expanded views when opening another?
Have a grid with a nestedViewTemplate but want just want onte nested item to be expanded at a time.

 

 

 

protected void RadGridUsers_ItemCommand(object source, GridCommandEventArgs e)
{
   if (e.CommandName == "ExpandCollapse")
   {
     foreach (GridTableView gtv in RadGridUsers.MasterTableView.DetailTables)
     {
       gtv.HierarchyDefaultExpanded = false;
     }

   GridDataItem item = (GridDataItem)e.Item;
   string strkey = item.GetDataKeyValue("UserID").ToString();
}

 

<telerik:RadGrid ID="RadGridUsers" runat="server"
AllowPaging="False" AutoGenerateColumns="False"
GridLines="None" Skin="Office2007" AllowMultiRowSelection="true"
OnItemCommand="RadGridUsers_ItemCommand"
OnDeleteCommand="RadGridUsers_DeleteCommand">
<MasterTableView CellSpacing="-1" DataKeyNames="UserID">
  <NoRecordsTemplate>
    Det fanns inga deltagare tillgängliga.
  </NoRecordsTemplate>
  <NestedViewTemplate>
    <asp:Panel ID="PanelUserInfo" runat="server"></asp:Panel>
  </NestedViewTemplate>
  <Columns>
    <telerik:GridClientSelectColumn UniqueName="column" DataTextField="UserId" />
    <telerik:GridBoundColumn HeaderText="Deltagare" UniqueName="column1" DataField="UsersName" />
    <telerik:GridBoundColumn HeaderText="Företag" UniqueName="column2" DataField="CompanyName" Visible="false" />
    <telerik:GridBoundColumn HeaderText="E-post" UniqueName="column3" DataField="Email" />
    <telerik:GridButtonColumn CommandName="Delete" ConfirmDialogType="RadWindow" ButtonType="ImageButton" UniqueName="Delete" Text="Ta bort" ConfirmText="Vill du verkligen ta bort denna deltagaren?" ConfirmTitle="Ta bort deltagare" />
   </Columns>
 </MasterTableView>
 <PagerStyle AlwaysVisible="true" />
 <ClientSettings>
   <Selecting AllowRowSelect="true" />
 </ClientSettings>
</telerik:RadGrid>

This doesn't work

Hello Daniel,

You can try out the following code to expand one parent row at a time:
c#:

protected void RadGrid1_ItemCommand(object source, Telerik.Web.UI.GridCommandEventArgs e)
    {
        if (e.CommandName == RadGrid.ExpandCollapseCommandName)
        {
            foreach (GridItem item in e.Item.OwnerTableView.Items)
            {
                if (item.Expanded && item != e.Item)
                {
                    item.Expanded = false;
                }
            }
        }

    }

Thanks
Princy.
