[Estanis]

Hello
I have a RadGrid created dynamically in aspx.
Get all the features of the columns of a table in my database and created the radgrid as has been defined.
More or less:

My problem now is that I want to include a filter of this type:

http://demos.telerik.com/aspnet-ajax/grid/examples/generalfeatures/headercontextfiltermenu/defaultcs.aspx

Do not know how I can dynamically create this part here is done in HTML.


 <HeaderTemplate>
                        <table>
                            <tr>
                                <td>
<asp:LinkButton ID="lnkSort" runat="server" CommandArgument="ShipCity" CommandName="Sort"
Text="Ship city"></asp:LinkButton>
                                </td>
                                <td>
                                    <img src="Img/Menu.gif" style="margin-top: 5px; margin-left: 5px; cursor: pointer"
                                        onclick='ShowColumnHeaderMenu(event,"ShipCity")' alt="Show context menu" />
                                </td>
                            </tr>
                        </table>
                    </HeaderTemplate>
                    <ItemTemplate>
                        <asp:Label ID="lblCity" runat="server" Text='<%#Eval("ShipCity") %>'></asp:Label>
                    </ItemTemplate>


Can you help? Thanks

Hello Estanis,

The header context filter menu can be enabled by setting the EnableHeaderContextFilterMenu property of the corresponding table view to true.

The code you posted implements showing the menu by left-clicking on an element that fires a client-side method (as in the ShipCity template column in the demo). To use this approach when creating the grid programmatically, you could create the corresponding header template dynamically in the code-behind and assign it to the HeaderTemplate property of the column.
Please examine the Programmatic creation help topic for additional information.

I hope this helps.

Best wishes,
