Why are GridGroupHeaderItem item indexes increased by 2 and not numerically sequential?

The following code iterates through all of the groupheaderitems in my RadGrid. I was originally having trouble expanding groups programmatically because I was attempting to expand based on sequential item.groupindex indexes, e.g. if (item.groupindex == "0" || item.groupindex == "1".

However, I found that the groupindex == "1" wasn't working so I wrote the following method to append all of the indexes to a stringbuilder:

protected void WeeklyGoalsGrid_PreRender(object sender, EventArgs e)
       {
           StringBuilder sb = new StringBuilder();
           foreach (GridGroupHeaderItem item in WeeklyGoalsGrid.MasterTableView.GetItems(GridItemType.GroupHeader))
           {
               sb.Append(item.GroupIndex);
           }           
       }

When I run the application, the stringbuilder contains {02468} and so on rather than what I thought should be {01234}

Does anyone know why the GroupHeaderItem indexes increase by two rather than by 1? This doesn't affect my code, as now I know what to look for, but I was just wondering about the reasoning behind this.

Thanks,

Josh

Hi,

I tried to replicate the issue by creating a sample project, but everything works as expected on my side. Could you give the project a try and let me know if I am missing something.

All the best,
