Hi Mike ,we are  using NetAdvantage 2009.2 version and both the them are from same version only .

Here is that code which fails populate “UltraGridRow drv” with grouping functionality in them name “Aero” .whereas same was working with them “WindowsXP - Silver”..Because it retains the row selection before/after grouping..Where as in “Aero” them it doesn’t retains the selection..While grouping the column. So the enumerator populate “UltraGridRow drv” with null value..Which causing

Problem while finding the cell values from drv object..which is null now …  J..which is not the case in them “WindowsXP - Silver”. ..it works ..for us ..:)

if (UltraGrid1.Selected.Rows.Count > 0)

{

 foreach (UltraGridRow drv in UltraGrid1.Selected.Rows)

{

 if (drv. Cells["Running Type"].Value.ToString() == "Server")

{

                      strDrIds += drv.Cells["DeviceRunningId"].Value.ToString() + ",";

               }

}

}

Let us know if there are any thing we are missing in property settings to retain the row selection before/after grouping the column ..it shouldn’t remove the selection after dropping the column into the grid  . Thanks

Hi,

When you say "Theme" here, are you refferring to changing the Operating system themes? Or loading an isl file into your application?

Either way, I can't see how either of these couple possibly affect the selection in the grid. In order to look into this, we will need you to provide a small sample project we can use to duplicate the issue, and more specific information about what Operating system you are running (assuming you are talking about O/S themes), or exactly which isl files you are using (if that's what you meant be themes).

Hi Mike,Thanks ..now i am able ...understand where is my mistake .. :) ..actually that property was inside the override settings ..n i was not able to find it ..earlier ..please ignore my last reply ..thanks for you help n support .

Solution : DisplayLayout.Override.SelectTypeGroupByRow = None

Hi Prasant, 

I ran your sample and I get the same results you do. But I'm still not clear on what you mean by "theme". These two grids clearly have different property settings. It looks like maybe you are talking about Presets when you say "theme".

I noticed that when I GroupBy on the first grid, the first GroupByRow in the grid gets selected and so therefore the data row that I selected before the grouping was de-selected. When you click the button, you are trying to access the cells collection of the selected rows and since a GroupByRow has no cells, you get an error. This is all perfectly normal and correct.

In the second grid, the GroupByRow is not selected and so it seems that the initial selected data row stays selected. The GroupByRow is probably not selected because the SelectTypeGroupByRow on the second grid has been set to None.
