Adding A Row To An Empty GridView?

I want to add a row inside an empty gridview, i tired the following code but no luck so far:

        GridViewRow oRow = new GridViewRow(0, 0, DataControlRowType.DataRow, DataControlRowState.Insert);
        TableCell oCell = new TableCell();
        oCell.Text = "XXX";
        oRow.Cells.Add(oCell);
        gvMemberShip.Controls.Add(oRow);

Note: i ran this code on Page_Load Event.

the way we did it is to extend the GridView. Override the CreateChildControls, with something like:

public class CustomGridView : GridView
{
    protected override int CreateChildControls(System.Collections.IEnumerable dataSource, bool dataBinding)
    {
        int numRows = base.CreateChildControls(dataSource, dataBinding);
        //no data rows created, create empty table
        if (numRows == 0)
        {
            //create table
            Table table = new Table();
            table.ID = this.ID;

            //create a new header row
            GridViewRow row = base.CreateRow(-1, -1, DataControlRowType.Header, DataControlRowState.Normal);

            //convert the exisiting columns into an array and initialize
            DataControlField[] fields = new DataControlField[this.Columns.Count];
            this.Columns.CopyTo(fields, 0);
            this.InitializeRow(row, fields);
            row.TableSection = TableRowSection.TableHeader;
            table.Rows.Add(row);
            this.Controls.Add(table);
        }
        return numRows;
    }
}

Overrides the GridView' CreateChildControls to Add an Empty table to it when there is no data to display.

You could use the DataSource of the GridView and initialize with a collection with only 1 element. If you do this in your Page_Load and then call DataBind() the GridView will show your row.
