Get value of hidden gridview into session variable

 Hello and thanks for any ideas on this in advance.

I have a hidden casegridview from a sqldatasource with 2 values (case_id, client_id)

 The case gridview datasource takes a client id parameter from a second gridview, client

I'm trying to get the case_id into a session variable and can't figure out how to do it.

I tried using onselectindexchange for gridview2 but that didn't return anything because gridview2 doesn't have select enabled.

I have this code for my client gridview that gets a client id into a session variable:


protected Sub GridView1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs)
        If Page.IsPostBack = True Then
            Dim i As Integer = GridView1.SelectedIndex
            'set  client id  from gridview into session variable
            Session("clientid") = GridView1.DataKeys(i).Value.ToString()
            Session("clientfname") = GridView1.Rows(i).Cells(2).Text.ToString()
            Session("clientlname") = GridView1.Rows(i).Cells(4).Text.ToString()
            '   (update client with the selected value from client gridview)
            DetailsView1.PageIndex = GridView1.SelectedIndex
        End If
    End Sub
Can I use this block to add a session variable for case id that is coming from gridview2? 
Any help is appreciated

What events are you allowing in your first gridview, then?  You need some event to do this.  If update, insert, etc. use the code in your post in one of those event handlers to get the value from your second gridview.

Good Luck and happy programming!

 Hi and thanks for the reply,

I tried using GridView2_SelectedIndexChanged , but that didn't return anything. I think it's because nothing in gridview 2 is selected, instead it changes according to the row selected in gridview1.

Here is the code that I tried:

Protected Sub GridView2_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs)
        'set  caseid  from gridview into session variable
        Dim caseid
        Session("case_id") = GridView2.SelectedValue
        caseid = Session("case_id")
        Label3.Text = Session("case_id")
    End Sub

  I used a label to test what case_id is returned. Is there a different event I should try?

Thanks for the advice.

Get Value from Hidden Column in Gridview control
I have managed to get the value from my hidden field by using the SelectedIndexChanged event and the following line of code:string keyValue = GridView1.SelectedDataKey.Value.ToString()I would however prefer to get access to the hidden column value on the GridView1_RowDataBound event, so that I can then evaluate each row against the hidden columns value and decide whether or not to display the edit button in each row.

Issue with getting values from child controls in a gridview, to use for the update using a SQLDataSource control
Hi all, I have a gridview bound with a SQLDataSource. I am using the Update feature of the SQLDataSource to update a SQL Server database with values entered into the gridview. However I am not getting it to work. I believe this is due to the controls that contain the user entries are not the gridview itself, but rather child controls within the gridview. I have been using the names of the actual controls but nothing happens. Upon submit, the screen returns blank, and the database is not updated. Here is some code:   <asp:GridView ID="GridEditSettlement" runat="server" AutoGenerate...
