adding multiple rows to a table dynamically via vb.net and ASP.net
OK so, Im trying to add data to a table that will eventually be exported to a database and I know there must be a for each statement added to this Im just not sure exactly how to do this. This is what I have thus far. It adds one line to the table but forgets it as soon as go to add anothert line.
I set up tablelist as a string array but Im not sure how to use it to do a "for each" in it to reconstruct the table when the page goes to its ispostback and should I add the code to the ispostback section in the page load sub.. I know Im on the right track but Im missing somethign stupid.
Here is my code
Private Sub AddDataAndTableRow()
Dim tr As New TableRow
WorkTable.Rows.Add(tr)
tr.Height = 25
Dim td1 As New TableCell
Dim td2 As New TableCell
Dim td3 As New TableCell
Try
Do Until CurrentColumnCount = 4
If CurrentColumnCount = 1 Then
td1.Text = txtbox1.Text
TableList(CurrentColumnCou
tr.Cells.Add(td1)
CurrentColumnCount = CurrentColumnCount + 1
ElseIf CurrentColumnCount = 2 Then
td2.Text = Convert.ToString(chkbox.Ch
TableList(CurrentColumnCou
tr.Cells.Add(td2)
CurrentColumnCount = CurrentColumnCount + 1
ElseIf CurrentColumnCount = 3 Then
td3.Text = txtbox2.Text
TableList(CurrentColumnCou
tr.Cells.Add(td3)
CurrentColumnCount = CurrentColumnCount + 1
'CurrentRowCount = WorkTable.Rows.Count
Else
CurrentColumnCount = 1
End If
If CurrentRowCount < 1 Then
End If
Loop
Catch ex As Exception
End Try
End Sub

Are your trying to dynamically create the html table structure and populate it with input controls first, then read those values back in after the postback?
Your code sample looks like you are attempting to do both at once.

Yes there are just two text boxes and a checkbox that go into the table however there are a couple of other textboxes that are being added to the array so the array however many rows and 6 columns but the table is only 3 columns.
The headers for the columns are already hard coded into the web page and they show up and when I add one line it shows up but I need it to remember the old data when I add a new line or, re-create the old data when I add a new line.

Figured it out myself
I work out 2 textboxes and a checkbox (only).
QN: What do you want to loop through?
