Hi Тimo,
When you are using custom grouping, you always need to assign a given item to its group manually. If you are using a data source, you can use the
ItemDataBound event to assign the new item to its group. Alternatively, you can group your data according to the values of a column. This is achieved by using
GroupDescriptors and in this case
EnableGrouping should be set to
true and
EnableCustomGrouping to
false. More information about grouping can be found in
this help article.
As to changing the caption of a column, yes, you should do a manual update after you change the
HeaderText:
However, this is not the desired behavior and the text should automatically update when you change it. Therefore, I have logged this to PITS as an issue and we will address it in a future release. Here is the link to the
PITS item. Your Telerik points have been updated.
As to your last question, there are known issues regarding this behavior that were previously logged. Here are the links to the PITS items:

I hope this will help you. Do not hesitate to write back if you have any additional questions.
