"RadGrid.MasterTableView.Columns.Clear();" and "RadGrid.Columns.Clear();" don't work

[Jorge]

Good morning!

My version of the telerik is RadControls for ASP.NET Ajax 2010 Q3.

I'm trying to remove columns that are inserted with the command gridProntuarios.MasterTableView.Columns.Add() of grid through the command "gridProntuarios.MasterTableView.Columns.Clear();" and
"gridProntuarios.Columns.Clear();" but don't work.

What would the solution for this trouble?

Thanks!

Hello Jorge,

I guess it is not possible to delete a Grid column which is already added in the Grid's Column collection. One suggestion will be to set its Visibile/Display property to false as shown below.

C#:

gridProntuarios.MasterTableView.GetColumn("ColumnUniqueName").Visible = false;

Or

gridProntuarios.MasterTableView.GetColumn("ColumnUniqueName").Visible = false;

Thanks,
Princy.
