RadGrid UseStaticHeaders with GridTemplateColumns

[Randy]

I've noticed some funny behavior when I combine the UseStaticHeaders and GridTemplateColumn configurations for the RadGrid.

The grid loses the header and the detail disappears on occasion as well.

Here is a snippet of code:

<telerik:RadGrid
runat="server"
ID="gridSample"
AutoGenerateColumns="false"
ShowHeader="true"
ShowFooter="false"
OnItemDataBound="gridSample_ItemDataBound"
OnNeedDataSource="gridSample_NeedDataSource"
>
<ClientSettings>
<Scrolling AllowScroll="true" ScrollHeight="400px" UseStaticHeaders="true" />
</ClientSettings>
<MasterTableView EnableNoRecordsTemplate="true">
<NoRecordsTemplate>
<asp:Label runat="server" Text="There is no file to review" />
</NoRecordsTemplate>
<Columns>
<telerik:GridTemplateColumn HeaderText="Name" UniqueName="Name">
<ItemTemplate>
<asp:Label runat="server" Text='<%# Eval("LastName") + ", " + Eval("FirstName") + " " + Eval("MiddleName") %>' />
</ItemTemplate>
<ItemStyle Width="45%" HorizontalAlign="Left" />
<HeaderStyle Width="45%" HorizontalAlign="Left" />
</telerik:GridTemplateColumn>
.

.

.

</Columns>
</MasterTableView>
</telerik:RadGrid>

I believe the sticking point is the use of static headers with the grid template columns. If I remove either the template columns or the UseStaticHeaders declarative, the problem goes away.

This is an older app that i am supporting and it is using the 2015.1.225.35 version of the assembly.

Hello,

I tried to replicate the issue but to no avail. You can find my test project attached, give it a try and see what is the difference in your case.

A couple of other factors to consider. The code is running in IE11 in compatibility mode. And the grids are located within RadWindows.

Hi,

I have updated the project and placed the grid in window. Then I tested it in IE compatibility mode, however, it is still working as expected.
