To add one more column to a grid and bind the data in the DataRowBound event using ASP.NET Web Forms,

In your ASPX page, open the markup and add a new or to the GridView. For demonstration purposes, let's assume you want to add a column for displaying the "Status" of each row. You can use a to achieve this.

In your code-behind file (C#), bind the data to the GridView. You can do this during the Page_Load event or any other appropriate event.

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        // Assuming you have a DataTable named "dataTable" with data to bind to the GridView
        GridView1.DataSource = dataTable;
        GridView1.DataBind();
    }
}

In the DataRowBound event, you can access the newly added column and set its value based on the data in the corresponding row.

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        // Access the Label control in the "Status" column
        Label lblStatus = (Label)e.Row.FindControl("LblStatus");

        // Assuming the "Status" information is available in the "Status" column of your data source
        DataRowView rowView = (DataRowView)e.Row.DataItem;
        string status = rowView["Status"].ToString();

        // Set the value of the Label control to the "Status" value
        lblStatus.Text = status;
    }
}
