发帖数: 4 | 2 Before the column is added to the grid, the grid should have been filled with
viewstate data. So adding a blank column with the same name would replace the
column already in there? I have to fire up the Reflector to confirm this. If
so, then the adding column operation should be moved inside the "if" block.

PIP, you are so strong in .NET. What do you do for a living?

DataGrid grid = new DataGrid() ;
grid.AutoGenerateColumns = false;
BoundColumn column = new BoundColumn() ;
column.HeaderText = "Name";
column.DataField = "Name";
grid.Columns.Add(column);
HtmlForm form1 = (HtmlForm)this.FindControl("Form1");
form1.Controls .Add(grid);
if (!IsPostBack)
{
Employee[] people = new Employee[] { new Employee("1", "Steve") , new
Employee("2", "John") , } ;
grid.DataSource = people;
grid.DataBind() ;
}
