//    you can add this code to the method which you want to create the DataTable and Bind the GridView

//create new DataTable
DataTable dt = new DataTable();

//create new DataColumn
DataColumn newColumn;

newColumn = new DataColumn();

//add type of the column
newColumn.DataType = Type.GetType("System.String");

//add column name
newColumn.ColumnName = "Firstname";

//add column to the DataTable
dt.Columns.Add(newColumn);

newColumn = new DataColumn();

newColumn.DataType = Type.GetType("System.String");

newColumn.ColumnName = "Lastname";

dt.Columns.Add(newColumn);

//create new row
DataRow newRow;

//assume that you have 2 ArrayList which are equal length
//convert ArrayList to Array
arrayFn = arrayListFn.ToArray();
arrayLn = arrayListLn.ToArray();

//add row to DataTable
for (int i = 0; i < arrayFn.Length; i++)

{

      newRow = dt.NewRow();

      string fn = arrayFn.GetValue(i).ToString();

      string ln = arrayLn.GetValue(i).ToString();

      newRow[0] = fn;

      newRow[1] = ln;

      dt.Rows.Add(newRow);

}


//bind DataTable to GridView
grdName.DataSource = dt;

grdName.DataBind();


//add text to LinkButton and Label
for (int i = 0; i < grdName.Rows.Count; i++)

{

      string fn = dt.Rows[i][0].ToString();

      string ln = dt.Rows[i][1].ToString();

      LinkButton lnkFn = (LinkButton)grdName.Rows[i].FindControl("lnkFirstName");

      lnkFn.Text = fn;

      Label lblLn = (Label)grdName.Rows[i].FindControl("lblLastName");

      lblLn.Text = ln;

     
//add PostBack Url and sending parameter to other page     
lnkFn.PostBackUrl = "~/showName.aspx?firstname=" + fn;

}
