Columns-without-checkboxes.png

In my radgrid I want to display filter,grouping,sorting options for columns. So I made EnableHeaderContextMenu="true".

<rad:RadGrid ID="myGrid" runat="server"

AllowSorting="True"

AutoGenerateColumns="false"

AllowPaging="True" GridLines="Both" GroupingEnabled="true" AllowFilteringByColumn="true"

EnableAJAX="True" EnableHeaderContextMenu="true" ShowGroupPanel="false" ShowFooter="True"

PageSize="20" EnableHeaderContextFilterMenu="true"

AllowMultiRowEdit="true" AllowMultiRowSelection="true"

OnNeedDataSource="myGrid_NeedDataSource"

OnDetailTableDataBind="myGrid_DetailedTableDataBind"

OnItemDataBound="myGrid_OnItemDataBound"

OnPreRender="myGrid_OnPreRender">

<ClientSettings EnableRowHoverStyle="true" Resizing-AllowColumnResize="True" AllowColumnsReorder="True"

ReorderColumnsOnClient="True" EnablePostBackOnRowClick="true">

<Selecting AllowRowSelect="True" />

<ClientEvents OnGridCreated="OnGridCreated" />

</ClientSettings>

The problem here is , it doesnt show checkboxed for displaying/hiding columns.
Where as other pages are working fine.

Appriciate your help.

Thanks

ASP:

In order to display the header context filter menu for a grid you should only need to set EnableHeaderContextMenu="true", as you've done.The list of the columns should be available to hide/display whether the columns are created dynamically or declaratively. However, each column's Visible property should be set to true (its default value).

I want to be sure you've referenced the Grid/Header Context Filter Menu online demo for insights.

Can you post more of your code to help in identifying the problem?

Cheers!

Hello,

Can you confirm that you do not have any styles on your page that could hide the checkboxes? Also, what is your RadControls version? I tried to replicate the problem using RadControls version Q1 2012 SP1 but to no avail. You can find my test page attached to this message.
