[Solved] Bug with Adding Column through Header Context Menu

[Simin]

In RadGrid, if EnableHeaderContextMenu is set to true and a GridColumn's Display attribute set to false, and HeaderStyle's Width attribute is set, the generated HTML colgroup style will not contain "display:none" style.  For example,

<telerik:RadGrid>

<MasterTableView EnableHeaderContextMenu="true" TableLayout="Fixed">

<Columns>

<telerik:GridBoundColumn Display="false">

<HeaderStyle Width="100"/>

</telerik:GridBoundColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

If you examine the generated html, you will see 

<colgroup>

<col style="width:100px"/>

</colgroup>

Adding a column with HeaderStyle's Width attribute set will result in the same incorrect html. 

However, if you hide one column through the header context menu, the generated html is correct:

<colgroup>

<col style="width:100px; display:none;"/>

</colgroup>

Is there workaround for this bug before it is fixed?

Thanks

Hello Simin,

I tried to reproduce the issue you depicted on my local version of this online demo of RadGrid (hiding the CustomerID column) but my attempts were not successful. The initially hidden column was not rendered at all as part the col group elements at all and was displayed at a later stage (see the enclosed screenshot).

Can you please test this case on your machine? Also compare the differences in both configurations and share them with me as they can help us pinpoint the source of the issue to eliminate it.
