passing gridview cell value to another page

Question

User1386166523 posted

Hello,

I have a GridView control on a Request2.aspx page. In the <Columns> section, there is a TemplateField showing project ids from the project table:

<asp:TemplateField ItemStyle-HorizontalAlign="Left" ItemStyle-Width="20%" HeaderText="Project ID">
    <ItemTemplate>
        <asp:LinkButton ID="Lbtn_Select" runat="server" Text='<%# Eval("projectid") %>'
            ToolTip="Click To View Details" PostBackUrl="~/Request2Detail.aspx"></asp:LinkButton>
    </ItemTemplate>
</asp:TemplateField>

Gridview is populated by assigning datatable as datasource to gridview. The gridview shows project ids as links and the control transfers to Request2Detail.aspx page. In Request2Detail.aspx, I have to show information of the project id that was clicked. However, I have not been able to pass the clicked project id value to the Request2Detail.aspx. Lbtn_Select.Text contains the project id for each row of Gridview. I read that through PostBackUrl property, we can access all controls of the previous page using Request object such as TextBox1.Text = Request.Form["TextBox1"].ToString();

However, projectid is a TemplateField within a gridview.

This assumes that there is no restriction in passing the projectid as a QueryString parameter.  Try this:

PostBackUrl='<%# Eval("projectid", "~/Request2Detail.aspx?id={0}") %>'

Then in the Request2Detail page, Request.QueryString("id);

Thanks a lot paindaasp. It worked perfectly with the following code:

//Request2.aspx
<ItemTemplate>
    <asp:LinkButton ID="Lbtn_Select" runat="server" Text='<%# Eval("projectid") %>'
        ToolTip="Click To View Details" PostBackUrl='<%# Eval("projectid", "~/Request2Detail.aspx?id={0}") %>'></asp:LinkButton>
</ItemTemplate>

//Request2Detail.aspx.cs
protected void Page_Load(object sender, EventArgs e)
{
    Response.Write(Request.QueryString["id"]);
}
