                                            ByVal colLast As Integer)
            For rowIndex As Integer = gridViewControl.Rows.Count - 2 To 0 Step -1
                Dim gvRow As GridViewRow = gridViewControl.Rows(rowIndex)
                Dim gvPreviousRow As GridViewRow = gridViewControl.Rows(rowIndex + 1)
                For cellCount As Integer = colStart To colLast
                    If gvRow.Cells(cellCount).Text = gvPreviousRow.Cells(cellCount).Text Then
                        If gvPreviousRow.Cells(cellCount).RowSpan < 2 Then
                            gvRow.Cells(cellCount).RowSpan = 2
                            gvRow.Cells(cellCount).RowSpan = gvPreviousRow.Cells(cellCount).RowSpan + 1
                        End If
                        gvPreviousRow.Cells(cellCount).Visible = False
                    End If

Accessing gridview cell values


Hi All,

In my application Iam using GridView, in this there are fields (Quantity, Price, Amount) the user can enter Quantity Field value which is a template field (textbox). Iam calculating Amount(Quantity * Price) using Javascript and assigning to the Amount Column cells as below

Gridviewcell.innerText=Quanity * price.

and when user clicks on the Save button I want to add these details of Gridview to the database.

For i=0 to GridView.rows.count-1

GridView.Rows(i).Cells(2).toString ( for Example)

Next i

It is not displaying the changed value instead it is displaying the default value before calculating the amount.

Before implementing the Javascript part, I had done this in the code behind and it was working fine... Now I just dont want the page to get load so I used javascript.

Can any one help me out in able to access the value of Gridview cells which are assigned using Javascript.

gridview sort on changed cell text


I have a gridview that is being databound by an SQLdatasource and on  RowDataBound i am doing a calculation and then setting


e.Row.cells(17).text = Result


However, when I go to sort it on the website it sorts it based off the previous values.


Cell(17) from the datasource reads in all 1's. The numbers I change it to range from 0 to 15. So when I click sort nothing changes because it sees it as all 1's.

How can i make the gridivew sort off the changed text values?
