Jagadeesh Bollabathini 2-Jan-12 6:52am

Dim RowIndex As Integer = 0
Dim i As Integer
If (ViewState("CurrentTable")) IsNot Nothing Then
dt = DirectCast(ViewState("CurrentTable"), DataTable)
Dim dtCurrentRow As DataRow = Nothing

If dt.Rows.Count > 0 Then
For i = 1 To dt.Rows.Count
Dim box1 As TextBox = DirectCast(dgv.Rows(RowIndex).Cells(1).FindControl("txtDescrip"), TextBox)
Dim box2 As TextBox = DirectCast(dgv.Rows(RowIndex).Cells(2).FindControl("txtDuration"), TextBox)
Dim box3 As TextBox = DirectCast(dgv.Rows(RowIndex).Cells(3).FindControl("txtPredesessor"), TextBox)
Dim box4 As TextBox = DirectCast(dgv.Rows(RowIndex).Cells(4).FindControl("txtType"), TextBox)
Dim box5 As TextBox = DirectCast(dgv.Rows(RowIndex).Cells(5).FindControl("txtLag"), TextBox)
Dim box6 As TextBox = DirectCast(dgv.Rows(RowIndex).Cells(6).FindControl("txtFlow_Steps_ID"), TextBox)
Dim box7 As TextBox = DirectCast(dgv.Rows(RowIndex).Cells(7).FindControl("txtUnique_ID"), TextBox)
dtCurrentRow = dt.NewRow()
dtCurrentRow("SRNO") = i + 1
dt.Rows(i - 1)("DESCRIPTION") = box1.Text
dt.Rows(i - 1)("DURATION") = box2.Text
dt.Rows(i - 1)("PREDESESSOR") = box3.Text
dt.Rows(i - 1)("TYPE") = box4.Text
dt.Rows(i - 1)("LAG") = box5.Text
dt.Rows(i - 1)("FLOW_STEPS_ID") = box6.Text
dt.Rows(i - 1)("UNIQUE_ID") = box7.Text
RowIndex = RowIndex + 1
Next i
dt.Rows.Add(dtCurrentRow)
ViewState("CurrentTable") = dt
dgv.DataSource = dt
dgv.DataBind()
Session("DS") = dt
End If
Else
Response.Write("ViewState is nothing")
End If

if you are using DataTable as DataSource for a GridView then try this..

Delete a row in DataTable First Then Bind the gridView again.

C#

DataTable dt = (DataTable)(GridView1.DataSource);
dt.Rows.RemoveAt(GridView1.Rows.Count - 1);
dt.AcceptChanges();
GridView1.DataSource = dt;
GridView1.DataBind();

this code will delete the new row added at the last of a GirdView. If you want to delete row of any other index then replace GridView1.Rows.Count - 1 with your index value.

hope it helps..
