How do you catch a GroupByExpressions Error?

[Nick]

Hi,
I'm creating a GroupBy expression dynamically based on user input:

RadGrid1.MasterTableView.GroupByExpressions.Add(txtUserInput.Text);

Occasionally the user gets this wrong which causes an error.
I simply want to catch this error in a try/catch block and handle it, but I'm not sure where to put the try/catch.
Any help would be appreciated.
Thanks,
Nick

Hi Nick,

You can wrap the snippet of code where you add the group by expression with a try-catch block:

try
{
    RadGrid1.MasterTableView.GroupByExpressions.Add(txtUserInput.Text);
    RadGrid1.Rebind();
}
catch (Exception ex)
{
    Label1.Text = "Error: " + ex.Message;
}
