column span starting from cell 4

Question

User219039814 posted

I want to give headings to girdview.

But i want to skip the first 2 columns and start my column span from the third column onwards.

Is there a method where i can specify the start and stop range for column span

GridViewRow row = new GridViewRow(0, 0, DataControlRowType.Header, DataControlRowState.Normal);
TableHeaderCell cell = new TableHeaderCell();
cell.Text = "First Year";
cell.ColumnSpan = 2;

row.Controls.Add(cell);

cell = new TableHeaderCell();
cell.ColumnSpan=2
cell.Text = "Second Year";

row.BackColor = ColorTranslator.FromHtml("#3AC0F2");

displayData.HeaderRow.Parent.Controls.AddAt(0, row);

Just add empty header cells before the others, with cell.Text = "";

(You are creating a table row.  Proper structure means that row should have the same number of cells as the other rows, as individual cells or as one of the cells combined into a span.  You want those initial empty cells to be there.)

Hi vijaylakshmi,

You can use the ColumnSpan and RemoveAt to control your column span from the third column.

  <asp:GridView ID="grid"  OnRowCreated="grid_RowCreated"   runat  ="server"></asp:GridView>

        protected void grid_RowCreated(object sender, GridViewRowEventArgs e)
        {
            if (e.Row.RowType == DataControlRowType.Header)
            {
                // colspan from third column.
                e.Row.Cells[2].ColumnSpan = 2;
                // remove the four column
                e.Row.Cells.RemoveAt(4);
            }

            //if (e.Row.RowType == DataControlRowType.DataRow)
            //{
            //}
        }
