Remove groupbyexpression programatically

[Gino Suarez]

Hi, I create a group like outlook grouping using groupbyexpression programatically when i press a button based on particular circunstances, but also i need to remove this new group created programatically. Actualy i have other 2 groupbyexpression defined in design time, i just need to remove new groups created in runtime hope you can help me.

Using tk_Grid.MasterTableView.GroupByExpressions.Clear(); i clear all the groups but i just to remove one at time

tk_Grid.MasterTableView.GroupByExpressions.Add(new GridGroupByExpression("CodigoPlanCuenta Group By CodigoPlanCuenta"));

Hi Gino,

You can try something like this:

RadGrid1.MasterTableView.GroupByExpressions.RemoveAt(2);
RadGrid1.Rebind();

I hope this helps,

In my case the Clear(); method throws an ArgumentOutOfRangeException.

.Remove() and RemoveAt() are the same.

What can be the reason?

I use toolbar to programmatically create and remove grouping.

Full code is below.

Thanks in advance

    GridGroupByExpression expr1 = new GridGroupByExpression(RadGrid1.Columns[1]);

RadGrid1.MasterTableView.GroupByExpressions.Add(expr1);

//this is fine.

But 

RadGrid1.MasterTableView.GroupByExpressions.Clear() .RemoveAt() throws the error.
