Hi all.

it’s been a long time since I wrote and I promise I will pick up the pace. But now lets get down to business how to hide columns in a grid view:

The first thing that comes to mind is going to the definition of the columns in the GridView, go to the column “Go” and put the Visible property to false. When you run the code and access the value we see that there is nothing in that cell. This is because since. NET “releases”  the binding  because it sees that the Visible property is false. We want the DataBinding we just don’t want to show the column. To solve this we will have to register to the  RowCreated event  as follows:

protected void Grid_RowCreated(object sender, GridViewRowEventArgs e)
        {
            if (e.Row.Cells.Count > 0)
            {
                e.Row.Cells[0].Visible = false;
            }
        }

This code will make sure that when a row is added the column with index 0 will be hidden.

Another and a better way in my opinion to solve this issue is using the DataBound event:

protected void Grid_DataBound(object sender, EventArgs e)
        {
            if (Grid.Columns[0].Visible)
            {
                Grid.Columns[0].Visible = false;
            }
        }
