Hi, i use the next GroupingDescriptors
Dim descriptor As New GroupDescriptor()
descriptor.GroupNames.Add("COLOR", ListSortDirection.Ascending)
Me.RGViewPO.GroupDescriptors.Add(descriptor)
and in the Q2 2010 work perfect but in Q3 2010 does not work
this is a big problem to me and need fix Immediately, my users have complained since the update and do not want to go back to Q2
I attach two print screen, the first is the RadGridView with the release Q2, The Grouping by color is perfect
the Second is the same RadGridView with the release Q3 but the makes the clustering based on the first column of the table and not by the color column
Dim descriptor As New GroupDescriptor()
descriptor.GroupNames.Add("COLOR", ListSortDirection.Ascending)
Me.RGViewPO.GroupDescriptors.Add(descriptor)
and in the Q2 2010 work perfect but in Q3 2010 does not work

Hello Fernando,
I haven't been able to replicate this issue. I have put together a simple exmaple using a person class and I can add a group descriptor which displays correctly. Please can you try the sample below. This is just a RadGridView on a form.
Look forward to hearing back from you.
Richard

thanks
for taking the time to answer my problem is that if I group by a column
other than the first, does not work because it only brings me the
contents of the first column, in the case to explain the column of
color don't is the first, then if I made the grouping but always taking the first though I specified to be that of color.
I was testing what I sent and it worked but when I did what I would group by the number and not by the nommbre of person, always followed by grouping by name: (

Hello Fernando,
I'm not sure if I understand you correctly. you are saying that you have a problem when you group by a column that is not the first column? Is that correct?
I have extended the simple sample to introduce an additinoal column, and also include a NULL value, and all grouping behaves correctly.
If you would like to try the sample I have incuded it below. If you find that this works correctly, please post a sample that replicates your situation so I can help further.
Many thanks
Richard

I solved my problem...
Each time you add a new record to the dataset I commanded to expand all the groups with the following code
Me.RadGridView.MasterTemplate.AutoExpandGroups = True
and for some reason that is why I grouped well
since then it occurred to me to send so refreshing mastertemplate
Me.RadGridView.MasterTemplate.Refresh ()
and ready! now if I grouped correctly.
Thank you very much, honestly this is the first forum I know of where a company helps the developers, I congratulate you and look forward to learning more here.
