The Table Web server control allows you to create server-programmable tables on ASP.NET pages. This tutorial will show you how to use Table Web server control in ASP.NET 2.0 and C#.
The Table Web server control allows you to create server-programmable tables on ASP.NET pages. The TableRow and TableCell Web server controls provide a way to display the actual content for the Table control. The Table control builds up a table by adding TableRows to the Rows collection of the table, and TableCells to the Cells collection of the row. You can add content to a table cell by adding controls to the Controls collection of the cell.
protected void Page_Load(object sender, EventArgs e)
{
// Generate rows and cells
int numrows = int.Parse(DropDown1.SelectedItem.Value);
int numcells = int.Parse(DropDown2.SelectedItem.Value);
for (int j=0; j<numrows; j++)
{
TableRow r = new TableRow();
for (int i=0; i<numcells; i++)
{
TableCell c = new TableCell();
c.Controls.Add(new LiteralControl("row " + j.ToString() + ", cell " + i.ToString()));
r.Cells.Add(c);
}
Table1.Rows.Add(r);
