Filtering shifts header causing misalignment

[Francisco Amador]

I've been trying to add a filter to this treelistview but have had this extra header spacer added automatically. Unfortunately it only appears when I filter and it causes the header to no longer be aligned with the content. It thought it may have been the rowindicator, but even after turning it on and off it is still displayed when filtering.

Hi Francisco,

Actually, this part of GridViewHeaderRow is called GridViewIndentCell. However, the behavior you experience is a bit strange and it is not the default one.
I have prepared an example for you following the structure from the attached picture and everything works as expected on my side. Please check the attached project and let me know how it differs from yours. 
 

All the best,

After some further running inspection of my code I have found the problem to be that I was attempting to group the TreeListView. That piece of code I had been using for filtering and grouping RadGridViews and had made it generic enough to work with GridViewDataControl. Since all my RadGridViews were working I had not tried to filter and group in this screen as well.

I have now added a check to make sure to not add a GroupDescriptor to the RadTreeListView. That has solved the display issue.
