Question

I have a datalist that bound to a database where now the label is change to a link button

<asp:DataList ID="DataList1" runat="server" DataSourceID="SqlDataSource1" >
<ItemTemplate>
<asp:LinkButton ID="LinkButton1" runat="server" Text='<%# Eval("username") %>'>
</asp:LinkButton>
.....some other datalist item 
</ItemTemplate>
</asp:DataList>

For this case I wanted the link button to fired up a new page where the Eval(“username”) value is passed to the new page.

I’m thinking about passing it using session such as ….

string any_variable ;
session["Picked_username_from_datalist"] = any_variable ;
response.redirect("newpage.aspx");

so that the variable that I’m going to pass using session can be manipulated.

But my problem is I have no idea how to assign the Text='<%# Eval(“username”) %> to the variable any_variable …..

~~ the assigned value for the variable is depends on the text of the databind that binded to the database …. for example … 1st linkbutton text is username1 , and the 2nd is username2 and so on based on my SQL select command …..

I need the selected Text='<%# Eval(“username”) %> so that I can manipulate the information to display another databind control based on the value.

Can anybody help me?

you can use onitemcommand=”DataList1_ItemCommand” event of DataList

<asp:DataList ID="DataList1" runat="server" DataSourceID="SqlDataSource1" onitemcommand="DataList1_ItemCommand" >
        <ItemTemplate>
        <asp:LinkButton ID="LinkButton1" runat="server" Text='<%# Eval("username") %>' CommandArgument='<%# Eval("username") %>' CommandName="Redirect">
        </asp:LinkButton>
        .....some other datalist item 
        </ItemTemplate>
        </asp:DataList>

server side code is

protected void DataList1_ItemCommand(object source, DataListCommandEventArgs e)
{
    if (e.CommandName == "Redirect")
    {
         Session["Picked_username_from_datalist"] = e.CommandArgument;
         Response.Redirect("newpage.aspx");
    }
}
