dynamically add column

Hi ,

If you are doing that in window application then you have firstly check one thing that -- can any post back occur after grid is bind. If yes, then inspite of declaring the datatable within the FillGrid() menthod  declare that DataTable as Public (i.e. globally) so as to avoid lossing of data on postback. It will help you in maintaining the Grid State.

OK..but still there is not much difference.. comment the ViewState lines and GridView1.Bind();

hi

i have pasted a sample code. hope it give you some idea on how to proceed...

public void FillGrid()
{
    ViewState["Data"] = null;

    DataTable dt = new DataTable();

    //Add Columns to the datatable
    dt.Columns.Add("Name");
    //Define a datarow for the datatable dt
    DataRow dr = dt.NewRow();

    //Now add the datarow to the datatable
    dr["Name"] = Textbox1.Text; //value from textbox on screen
    dt.Rows.Add(dr);

    ViewState["Data"] = dt;

    GridView1.DataSource = dt;
    GridView1.Bind();
}
