Question

I have following code:

<asp:Button ID="InsertButton" runat="server" CausesValidation="True" 
                                    CommandName="Insert" Text="Add Form" 
             PostBackUrl="~/APPLICATION/FormView.aspx?postquestion="/>   

I using FormView Control.

I need to add Request.QueryString[“postquestion”] variable into “FormView.aspx?postquestion=” for PostBackUrl.

I found following code on net, however it’s not working:

PostBackUrl='<%# ="~/APPLICATION/FormView.aspx?postquestion=" + Request.QueryString  ["postquestion"].ToString() %>'

Thanks for help!

Answer 1

Try assigning the PostBackUrl like this instead:

<asp:Button ID="InsertButton" runat="server" 
    CausesValidation="True" 
    CommandName="Insert" 
    Text="Add Form"          
    PostBackUrl='<%# string.Format("~/APPLICATION/FormView.aspx?postquestion={0}", Request.QueryString["postquestion"]) %>' />
