Header Context Menu - Columns not hiding when checked

[Lee Malo]

I have a RadGrid with columns being added programatically in the page_load. Everything works but if I check a column the menu disappears and the column doesnt hide.
Any suggestions?

Hi,

Could you make sure that you are following a similar approach to enable the Header Context Menu.This is working fine on my end

C#

 protected void Page_Load(object sender, EventArgs e)
    {
      if ( !IsPostBack )
     {
       RadGrid1.DataSourceID = "SqlDataSource1";
       RadGrid1.MasterTableView.DataKeyNames = new string[] { "CustomerID" };
       RadGrid1.Width = Unit.Percentage(98);
       RadGrid1.PageSize = 5;
       RadGrid1.AllowPaging = true;
       RadGrid1.PagerStyle.Mode = GridPagerMode.NextPrevAndNumeric;
       RadGrid1.AutoGenerateColumns = false;
       RadGrid1.Skin = "Web20";
       //Add Customers table
       RadGrid1.MasterTableView.PageSize = 15;
       RadGrid1.MasterTableView.EnableHeaderContextMenu = true;
       RadGrid1.MasterTableView.Width = Unit.Percentage(100);
       GridBoundColumn boundColumn;
       boundColumn = new GridBoundColumn();
       RadGrid1.MasterTableView.Columns.Add(boundColumn);
       boundColumn.DataField = "CustomerID";
       boundColumn.HeaderText = "CustomerID";
       boundColumn = new GridBoundColumn();
       RadGrid1.MasterTableView.Columns.Add(boundColumn);
       boundColumn.DataField = "ContactName";
       boundColumn.HeaderText = "Contact Name";

      }
   }

Hi,

I have just come across the same problem, just upgraded to 2010.1.309.35 from 2009.3.1103.35.  Worked fine in the older version, in the new version when clicked on the item in the menu nothing happens and the menu closes.

<!-- HTML -->
    <telerik:RadGrid ID="RadOrders" runat="server" AllowPaging="True"  PageSize="30">
    </telerik:RadGrid>

<!--Code Behind-->
            RadOrders.DataSource = somedatasource;
            RadOrders.MasterTableView.DataKeyNames = new string[] { "OrderID" };

            // RadGrid Styles
            RadOrders.Width = Unit.Percentage(100);
            RadOrders.PageSize = 10;
            RadOrders.AllowPaging = true;
            RadOrders.AutoGenerateColumns = false;
            RadOrders.Skin = "Default";
            RadOrders.EnableHeaderContextMenu = true;

            RadOrders.MasterTableView.Width = Unit.Pixel(100);
            RadOrders.ClientSettings.Scrolling.AllowScroll = true;
            RadOrders.ClientSettings.Scrolling.UseStaticHeaders = true;
            RadOrders.ClientSettings.Scrolling.SaveScrollPosition = true;
            RadOrders.ClientSettings.EnableRowHoverStyle = true;
            RadOrders.ClientSettings.AllowColumnHide = true;

            // RadGrid Columns
            GridBoundColumn boundColumn = new GridBoundColumn();
            boundColumn.DataField = "Style";
            boundColumn.HeaderText = "Style";
            boundColumn.HeaderStyle.Width = boundColumn.ItemStyle.Width = Unit.Pixel(120);
            RadOrders.MasterTableView.Columns.Add(boundColumn);
            boundColumn = new GridBoundColumn();
            boundColumn.DataField = "PO";
            boundColumn.HeaderText = "P.O.";
            boundColumn.HeaderStyle.Width = boundColumn.ItemStyle.Width = Unit.Pixel(60);
            RadOrders.MasterTableView.Columns.Add(boundColumn);
            boundColumn = new GridBoundColumn();
            boundColumn.DataField = "Cons";
            boundColumn.HeaderText = "Docket";
            boundColumn.HeaderStyle.Width = boundColumn.ItemStyle.Width = Unit.Pixel(60);
            RadOrders.MasterTableView.Columns.Add(boundColumn);
            boundColumn = new GridBoundColumn();
            boundColumn.DataField = "Splr";
            boundColumn.HeaderText = "Supplier";
            boundColumn.HeaderStyle.Width = boundColumn.ItemStyle.Width = Unit.Pixel(200);
            RadOrders.MasterTableView.Columns.Add(boundColumn);
            boundColumn = new GridBoundColumn();
            boundColumn.DataField = "Qty";
            boundColumn.HeaderText = "Qty.";
            boundColumn.HeaderStyle.Width = boundColumn.ItemStyle.Width = Unit.Pixel(60);
            RadOrders.MasterTableView.Columns.Add(boundColumn);
            boundColumn = new GridBoundColumn();
            boundColumn.DataField = "Description";
            boundColumn.HeaderText = "Description";
            boundColumn.ItemStyle.Width = boundColumn.HeaderStyle.Width = Unit.Pixel(250);
            RadOrders.MasterTableView.Columns.Add(boundColumn);

            RadOrders.DataBind();


Not recieving any javascript errors, could i be missing any thing that has been added to the new version?

Hello Lee,

Could you take a look at the help article and our online examples on the programmatic creation of the grid. If you are creating the grid on Page_Load you need to be adding the columns to the MasterTableView first and then set their properties in order for their ViewState to be tracked correctly. In addition, you should remove the DataBind() call from the grid-creation code as it is not needed as explained in the online examples on Simple and Advanced databinding and their related help articles.

I hope this information helps.
