Unable to disable GROUPING

[Pei Chen]

Hi,

I want to disable "grouping" function.  For some reason, I keep getting it no matter I set GroupingEnabled="False" on grid,
adding Groupable="false" to columns and AllowDragToGroup="false" in clientSettings.  It allows me to drag the header and then will return a javascript error "'this.get_element()' is null or not an object".  Please help how to set GROUPING off.  thanks!!

Hello Pei Chen,

I didn't experience this issue, when I tried the same in my application. One suggestion in your case is attach OnCommand client event and check for the CommandName whether it is 'GroupByColumn' and then cancel the evnt, which in turn cacel the grouping funtion.

javascript:

    function OnCommand(sender,args) {
        if (args.get_commandName()=="GroupByColumn")
        {
            args.set_cancel(true);
        }
    }

I found a forum which discusses similar kind of issue. Please go through this forum.

Shinu.

Hi Shinu,

Thanks for your reply.  I finally found the culprit.  It's this property:
AllowColumnsReorder="True"

Once I remove it, the DragToGroup function turned off.  I forgot why I put that in there.  The sorting looks fine without it.  Can you tell me what this is for? and it is necessary for sorting?

Thanks,
Pei
