Try this:



<asp:datagrid id="MessageBoardRepeater" runat="server"> 


<Columns> 


<asp:TemplateColumn HeaderStyle-Width="7%" HeaderText="Case No"> 


<ItemTemplate> 


<asp:HyperLink text='<%# DataBinder.Eval(Container.DataItem, "title") %>' NavigateUrl= '<%# "Thread.aspx?id=" & DataBinder.Eval(Container.DataItem, "threadId") %>' Runat="server" /> 


</ItemTemplate> 


</asp:TemplateColumn> 


</Columns> 


</asp:datagrid>

Remember that the HyperlinkColumn can be found during the ItemDataBound Event. You are surely familiar with how to use this Event Handler, so I'll provide an example of code to use for the Item and Alternating ListItemTypes:



    Private Sub dgrdProducts_ItemDataBound(ByVal sender As Object, ByVal e As DataGridItemEventArgs) Handles dgrdProducts.ItemDataBound


        Dim item As ListItemType = e.Item.ItemType





        If item = ListItemType.Item Or item = ListItemType.AlternatingItem Then


            Dim hl As HyperLink = e.Item.Cells(0).Controls(0)





            hl.NavigateUrl = "bogus.aspx?prodid=" & e.Item.DataItem("ProductID") & "&supplid=" & e.Item.DataItem("SupplierID")





        End If





    End Sub

The HL-Column is made up of Hyperlinks, so you'll need to find them. In my example, The first Control of the first Cell is a Hyperlink, as my Hyperlink Column is my First Column. You may now add as many arguments as you like to your hyperlink.

Hmmm. But that only allows you to pass one parameter right? I tried to use multiple parameters but that doesn't work. Someone mentioned the use of an asp template column. That should be ok, but how do you pass another value in the same row in the same query string? The above example throws an index error if i tried {1}.

In case you are using HyperlinkColumn as



<asp:DataGrid id="DataGrid1" AutoGenerateColumns="False" runat="server">


<Columns>


	<asp:HyperLinkColumn HeaderText="ID" DataNavigateUrlField="ID" 


	DataNavigateUrlFormatString="link.aspx?id={0}" 


	DataTextField="ID"></asp:HyperLinkColumn>


</Columns>


</asp:DataGrid>

You can write
Response.Write(Request.queryString("id"))

Is this the way you are trying it
or are you having Hyperlink as <asp:hyperlink runat=server.... >

Using values from hyperlink column in a query string

steo009 — Sat, 02 Aug 2003 23:55:42 GMT

Hi All!

I just made a column in my datagrid a hyperlink column but I can't seem to use those values in the column in a query string anymore. Before I just used e.items[1].text to get it but thats not working anymore since I guess its now a hyperlink not plain text. How can I get the actual text of the hyperlink? Any help would be great!

Thanks :)
