Replacing a column throws exception

[Andrew]

Hello,

I am pretty sure this used to work before.

this.radGridView.Columns[0] = new GridViewDataColumn();

Now it throws a System.IndexOufOfRange exception, message "Index was outside the bounds of the array"

My version is 2011.1.419.1040

Hi Ken,

You need to add a column like follows:

this.RadGridView1.Columns.Add(new GridViewDataColumn(){DisplayIndex = 0});

The DisplayIndex property will define at which position the column will be displayed.

Thank you for the fast response.

DisplayIndex looks a bit weird to use, can you please tell what are the reasons behind this change?

I got side tracked by your answer, actually adding is not what I need. I need to replace a column. 

So going back to my original question, how can I replace a column?

Hello Ken,

If you want to replace a column, you may remove it first and add a new only with the exact same display index:

this.clubsGrid.Columns.RemoveAt(1);
this.clubsGrid.Columns.Add(new GridViewDataColumn() { DataMemberBinding = new Binding("Name"), DisplayIndex = 1 });
