Is it possible to sort column values, rather than by absolute value of column value, by a function of the column value?
Also, when I sort, I automatically want it be grouped by the sort criteria. But in some cases, I want some sort criteria to be explicit. For example when the user clicks on user name, I wish to sort by user name and date.
Thanks

Hello Umaa,
You can check this help article, which illustrates how to achieve custom sorting. Regarding the grouping please take a look at this article.

Thanks... Great Documentation...
I had couple of more Qs...
1) How do i disable user to enable grouping, ie provide grouping only programmatically. So I want to disallow dragging of columns and the top row, available for columns to be dragged over
2) When I group, I would like to group by coding the column value, but display should be decode back.
By this I mean, for example
custType = "Good" "Excellent" ...
group using codes say 1, 2,
but display actual text.
Thanks

Hi Umaa Krishnan,
On question #1 :
You need to set a single property to prevent user initiated grouping :
RadGridView.ShowGroupPanel = false;
On question #2:
To control the value displayed in the group header you may use the RadGridView.GroupHeaderTemplate property.
This way you can place a textblock in the header , bound to the Header property via custom IValueConverter . This converter will do the translation between underlying value and displayed value.
Let me know in case you need further assistance on implementing these.
