Hi,

I have a RadGridView with merge column headers displayed on a screen. There's a button to export the grid to html file and all is working fine if I use the instance of RadGridView currently displayed. I need to clone the current instance of the grid and use this cloned instance to export to html file. When I clone the grid, I created a new instance of the grid programatically and copied all the settings including the ColumnGroups & the ColumnGroupName of each column. The problem is that when I export the cloned grid, the merge column header are not being displayed in the export file. Is there any workaround for this issue?

Thanks,
Sherwin

Hello Yoan,

In my application, the RadGridView ItemSource is bound to DomainDatasource via WCF RIA Services with paging enabled. When exporting, I have an option to export the current page or all records. I need to clone the grid only when exporting all records. I do this so that it will not refresh the current state of the grid like the page no., etc. In short, I do this for better user experience. 

Anyway, is there a method I can call in RadGridView or a way to load the merged headers without displaying it in the UI?

Thanks,

Hi Sherwin,

It turns out that the merged headers rely on the already rendered GridView's Columns.
