Group One Column at a Time

[steve_ba14]

Good Morning,

Does anyone know of a way to limit the grouping of a Grid.

I have a complex dataset which fails when a second grouping is added to the Grid. I would like to enable grouping but force the user to only group by one column at a time.

Any Ideas?

Hi Steven,

What you can do is to use the OnDataBinding event. If the groups object provided by the Grid client object are more than one then you prevent the event.
e.g.

function onDataBinding(e)
{
    if($("#YourGrid").data('tGrid').groups.length > 1 )
    {
        e.preventDefault();
    }
}

I hope this helps.

Thanks for the code.

However, preventing the grouping by blocking the onDataBinding event still leaves the UI out of sync. (I.E. the last prevented grouping is still visible on the grouping bar).

Is there an easy way to fix this also?

Cheers

Steven

Edit

I have added the line 

  $(".t-group-delete").last().click()

and it works okay.
