Render grid with a group column by default; I do not want the drag and drop option on UI

[Greg]

Hello,

In the basic demo for the grid, it allows drag and drop of column headers for making the grid group by those columns.  What I would like, is to have the grid already grouped by a column when the UI has initially rendered, and not have the drag and drop or ability to remove the group column.  How could I do this?

Another way I was thinking of rendering the data in the grid, was that column1 would be my group column, and column2 would contain a grid of the items within that group.  But, I do not see a rowDataBound event on the grid to help construct this.

Thank you

Hi Greg,

As you may know, the dataSource component is responsible for the data operations, thus in order to group the grid component, a group expression should be added to the dataSource. 

In order to hide the grid's group bar you should set groupable options to false or omitted completely.

Here is a short example:

All the best,

(different Greg here) I have to say, I love the group-by feature. I was at a demo for a web layer over SAP data and this was one of the things their web ui could do - drag and drop columns to do group by. This will be very nice for looking at all of the financial data we have.

Okay, I see.  Works nicely, thank you for the prompt and accurate reply.

Hi!

this solution functions in my project.

i need more help... can i configure any categories closed? (aria-expand= "false")

Hi ,

You can handle the dataBound event, and programmatically close all groups, matching some custom condition, via the collapseGroup() method, e.g.:

http://dojo.telerik.com/ocElE/2

The mentioned ARIA attribute will be changed accordingly (to aria-expand="false");

I hope this helps.
