Dim str As String
Dim str1 As String
sql = "select distinct semid from matrix where courseid=" & DdlCourseWise.SelectedValue & ""

If dt.Rows.Count = 0 Then
dt.Dispose()
Amit.Messagebx.Alert(Me, "No Data Available")
Exit Sub
End If

For k = 0 To dt.Rows.Count - 1
sem += dt.Rows.Item(k)("semid").ToString + ","
Next
sem = Left(sem, sem.Length - 1)
Dim sid As String() = Split(sem, ",")

For k = 0 To dt.Rows.Count - 1
str += "R" + dt.Rows.Item(k)("semid").ToString + ".RowNumber as Sno," + "R" + dt.Rows.Item(k)("semid").ToString + ".AdmissionNo," + "R" + dt.Rows.Item(k)("semid").ToString + ".RoomNo" + ","
If str1 Is Nothing Then
str1 += "(Select RoomNo,AdmissionNo, ROW_NUMBER() OVER (ORDER BY Matrix.CourseId) 'RowNumber' FROM Matrix inner join student on student.studentid=matrix.studentid WHERE Matrix.CourseId = " & DdlCourseWise.SelectedValue & " and Matrix.SemId = " + dt.Rows.Item(k)("semid").ToString + ") AS " + "R" + dt.Rows.Item(k)("semid").ToString + ""

When filling datatable, if there are same column name in the datasource then it will add numbers to that.

You can change the gridview header in the Databound event

C#

protected void Gridview2_DataBound(object sender, EventArgs e)
     {

         foreach (TableCell cl in Gridview2.HeaderRow.Cells)
         {
             if (cl.Text.StartsWith("SNo"))
                 cl.Text = "SNo";

             if (cl.Text.StartsWith("RoomNo"))
                 cl.Text = "RoomNo";

         }
     }
