I have a gridview which has varing numbers of row and columns. I have "select" link in my gridview whcih opens up a whole new window The problem I have is I would like to display just the line I have selected in the new window. I have tried various different thing with not much luck. Any help of this would be great.

Code I have in Main aspx.vb:

  '--Pop-Up-Window
            Dim queryString As String = "Popup.aspx"
            Dim newWin As String = "window.open('" & queryString & "');"
            ClientScript.RegisterStartupScript(Me.GetType(), "pop", newWin, True)

Code I have in main html:

            <asp:GridView CssClass = "gridview" ID="GridView1" runat="server">
                <HeaderStyle BackColor = "#507CD1" Font-Bold="True" ForeColor="White" />
                <AlternatingRowStyle BackColor = "#BFE4FF" />

                            <Columns>
                    <asp:TemplateField HeaderText = " " >
                        <ItemTemplate>
                            <%# Container.DataItemIndex + 1 %>
                        </ItemTemplate>
                    </asp:TemplateField>

                    <asp:TemplateField HeaderText = " " >
                        <ItemTemplate>
                            <asp:LinkButton CssClass="a" ID="LinkButton3" Text="Select" runat="server" CommandName="Select" CommandArgument="<%# Container.DataItemIndex %>" OnClick="LinkButton3_Click" />
                        </ItemTemplate>
                    </asp:TemplateField>
                </Columns>

            </aspGridView>

You have to pass something to the new popup page.

Dim theId As String = "123"
Dim queryString As String = "taxPopup.aspx?id=" & theId

Or use a link rather than a linkbutton.  With a linkbutton you have to postback then execute JavqaScript.  A simple link will be much easier.

Thanks for your reply. I found this code for a hyperlink.

<asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl='<%# Bind("LeadID") + Request.QueryString("type") %>'Text=""/>

What do I replace "LeadID" an "Type" with ?

Thanks

Build a proper URL.  Perhaps use string concatenation.

Great thanks. The  link is  now working. I want to display

certain data from my gridview in my main aspx page. How do I do this without recreating a gridview. can I link the two aspx pages?

Great thanks. The pop up id now working. do I need to still use the code u sent to link the two pages now that I am using a hyperlink?

I have no idea what you are asking.  It sounds like the code is working and you are able to pass data in the URL querystring.

Hi  E.RU,

According to your description, I still couldn’t understand your requirement clearly.

If you don't want to display the new page by using Gridview, you could use html table control.

You could send the data from mail page to new page by using hyperlink’s query string.

Then you could use request.querystring to get the data in the new page’s page load event, and bind the data to a html table control.

More details,  you could refer to below codes:

Main ASPX Page:

<asp:GridView ID="GridView1" runat="server">
            <HeaderStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />
            <AlternatingRowStyle BackColor="#BFE4FF" />
            <Columns>
                <asp:TemplateField HeaderText=" ">
                    <ItemTemplate>
                        <asp:HyperLink ID="declare_id" runat="server" Text=' <%#Eval("LoginId") %>'
                            NavigateUrl=' <%# "Popup.aspx?LoginId=" + Eval("LoginId")+"&Name="+Eval("Name")+"&Mail="+Eval("Mail") %>'> </asp:HyperLink>
                    </ItemTemplate>
                </asp:TemplateField>
                <asp:BoundField HeaderText="HRID" ItemStyle-Width="110px" ItemStyle-CssClass="HRID" DataField="LoginId">
                    <ItemStyle CssClass="HRID" Width="110px"></ItemStyle>
                </asp:BoundField>
                <asp:BoundField HeaderText="Name" ItemStyle-Width="110px" ItemStyle-CssClass="Name" DataField="Name">
                    <ItemStyle CssClass="Name" Width="110px"></ItemStyle>
                </asp:BoundField>
                <asp:BoundField HeaderText="Mail" ItemStyle-Width="110px" ItemStyle-CssClass="Mail" DataField="Mail">
                    <ItemStyle CssClass="Mail" Width="110px"></ItemStyle>
                </asp:BoundField>
            </Columns>
</asp:GridView>

New ASPX Page's code behind:

Private Sub SurroundingSub()
    //Get the parameters passed by the URL
    Dim LoginId As String = Request.QueryString("LoginId")
    Dim Name As String = Request.QueryString("Name")
    Dim Mail As String = Request.QueryString("Mail")
    //Create header rows
    Dim trHead As HtmlTableRow = New HtmlTableRow()
    //Create header cells
    Dim tcHeadLoginID As HtmlTableCell = New HtmlTableCell()
    Dim tcHeadName As HtmlTableCell = New HtmlTableCell()
    Dim tcHeadMail As HtmlTableCell = New HtmlTableCell()
    //Assign values to header cells
    tcHeadLoginID.InnerHtml = "LoginId"
    tcHeadName.InnerHtml = "Name"
    tcHeadMail.InnerHtml = "Mail"
    trHead.Cells.Add(tcHeadLoginID)
    trHead.Cells.Add(tcHeadName)
    trHead.Cells.Add(tcHeadMail)
    Table2.Rows.Add(trHead)
    //Create data rows
    Dim tr1 As HtmlTableRow = New HtmlTableRow()
    Dim tc11 As HtmlTableCell = New HtmlTableCell()
    Dim tc12 As HtmlTableCell = New HtmlTableCell()
    Dim tc13 As HtmlTableCell = New HtmlTableCell()
    //Assign values to data cells
    tc11.InnerHtml = LoginId
    tc12.InnerHtml = Name
    tc13.InnerHtml = Mail
    tr1.Cells.Add(tc11)
    tr1.Cells.Add(tc12)
    tr1.Cells.Add(tc13)
    Table2.Rows.Add(tr1)
End Sub

Result:

Best Regards,
