passing seleced rows from gridview to another page

  #1  
May 20th, 2008
hello, I 'm still a noob at programming in vb.net
I have a little problem. I 'm trying to get my selected rows to another page. I already can select my rows with checkboxes but I don't know how I can pass them through a session to another page.
hopefully someone can help me.

Hi majestic

I looked at the link you gave me, but they only discuss the way to pass the values through querystrings, but I like to pass my values through sessions, so I don't need to add something extra in my URL

I think the second post on that link is what you need:

Help with Code Tags
VB Syntax (Toggle Plain Text) 
  1. Dim gridrow As GridViewRow = GridView1.SelectedRow
  2.  
  3. Session.Add("Value1", gridrow.Cells(0).Text)
  4.  
  5. Session.Add("Value2", gridrow.Cells(4).Text)
  6.  
  7. Response.Redirect("TestPage.aspx")
  8.  
  9. End Sub

I 've tried your code you gave me, but I don't want to get one value at a time out of my gridview. My problem is, I select multiple rows with my checkbox and I want to get the selected rows in on time and pass them to another page.

I want to past my selected rows from my firstpage.aspx to a secondpage.aspx. I already got the code to put my values in an array and send the array to my secondpage.aspx with an session but I can't get the values out of my array on the secondpage.aspx. I get an error: nullreferenceexception was unhandled by user code.
This is my code I use on my secondpage.aspx to get the values out of my array and try to put them into a table.
Help with Code Tags
vb.net Syntax (Toggle Plain Text) 
  1.         'variabelen in tabel inlezen
  2.         Dim hshToestel As Hashtable
  3.         hshToestel = Session("Reservatie")
  4.         For Each oToestel As clstblToestellen In hshToestel
  5.             Dim tr As New TableRow
  6.             tr.Cells.Add(oToestel.fnSelect)
  7.             tblReservatie.Rows.Add(tr)
  8.         Next
