What exactly is your question? So you want to pass values from the selected row in the gridview to another page?

 

[yosie2007]

Yes that is my question and then when the selected value passed to the second page I have a form for the user to fill out and submit by e-mail.I just need to know how to select from multiple check boxes and pass it to next page. thanks

You can have a button, that when pressed will get the data. Use the RowDataBound event of the grid. As each row binds, get a reference to the checkbox. Then check if it is checked or not. If it is, you can add the values to an array or collection, or datatable.. or what ever, and pass that in a sesion variable to the next page.

thank you jbenson001 for the tip. can you give me a sample code to start with . I am struggling with this code
Protected Sub btnButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnButton.Click
'Error: Converting Methods, Functions and Constructors
'Error: Converting If-Else-End If Blocks

' StringBuilder object
Dim str As StringBuilder = New StringBuilder()

' Select the checkboxes from the GridView control
Dim i As Integer
For i = 0 To gvPlansProposal.Rows.Count - 1 Step i + 1
Dim row As GridViewRow = gvPlansProposal.Rows(i)
Dim isChecked As Boolean
If isChecked = (CType(row.FindControl("CheckBox1"), CheckBox)).Checked Then

End If


' If (isChecked) Then

' Column 2 is the name column
str.Append(gvPlansProposal.Rows(i).Cells(2).Text)
' End If
Next

' prints out the result
Response.Write(str.ToString())

End Sub

Use the RowDataBound event of the grid
[/quote Me]

    Protected Sub gvPlansProposal_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles gvPlansProposal.RowDataBound
        If e.Row.RowType = DataControlRowType.DataRow Then
            Dim cb As New CheckBox
            cb = e.Row.FindControl("CheckBox1")

            If cb.Checked Then
                ''add the values you want from e.Row.Cells(index#).Text to some collection
                ''then add to a session var. which will be available to you on the next page
            End If
        End If
    End Sub

thank you again for the help. for some reason even if I checked the check box I am getting false for all of them and the code is not executing. thanks

Are you checking for a postback on your page load event?

Yes, Mark
Is that the reason why this code is not executing?

Protected Sub Page_Load1(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

If Not IsPostBack Then
PopulatePlanProposalGridView()
End If


End Sub
Is that the reason why this code is not executing. It does not even get in between this line

If cb.Checked Then
Dim Test As String = e.Row.Cells(2).Text
''add the values you want from e.Row.Cells(index#).Text to some collection
''then add to a session var. which will be available to you on the next page
End If


Protected Sub gvPlansProposal_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles gvPlansProposal.RowDataBound
If e.Row.RowType = DataControlRowType.DataRow Then
Dim cb As New CheckBox
cb = e.Row.FindControl("CheckBox1")
If cb.Checked Then
Dim Test As String = e.Row.Cells(2).Text
''add the values you want from e.Row.Cells(index#).Text to some collection
''then add to a session var. which will be available to you on the next page
End If
End If
Response.Write("Test")
End Sub
