Hi i am using radgrid.
I have two questions regarding this.

I have different dataset and single grid.
so I have not defined columns in the grid.
Columns are generated through the dataset columns.

1. Now i want to hide the first column of the grid.
2. I want to add a column for deleting the record.

How can i do this?
Please suggest me some idea...

Hi DK,

I assume you want to hide AutoGeneratedColumn from code behind. If so please try the following code snippet:
C#:
protected void RadGrid1_PreRender(object sender, EventArgs e)
{
    if (RadGrid1.MasterTableView.RenderColumns.Length > 2) {
        RadGrid1.MasterTableView.RenderColumns(2).Display = false;
    }
}

About your second question, please refer to these articles, for more information about how to achieve your goal.

I hope this helps.

Hi DK,

Try replacing the above code as shown below and see if it helps:
c#:
RadGrid1.MasterTableView.RenderColumns[2].Display = false

You can also use the following code to hide a column using the UniqueName of the column which is the same as the Datafield name of the column:
RadGrid1.MasterTableView.GetColumn("ColumnDataFieldName").Display = false;

Thanks
Princy.

WBSRadGrid.MasterTableView.GetColumn("ActualEndDate").Visible = false;
//or
            WBSRadGrid.MasterTableView.Columns.FindByUniqueName("ActualEndDate").Visible 

= false;
