Then You better ask third pary tool developing team..!

As you are using the 3rd party tool first check tht it is supported for such type..!

BTW You didnt mention the 3 rd party vendor name so tht if any one uses the 3rd party tool before they can help You..!

What is the problem.... load the page using Webbrowser control of your windows application and invoke the items which you need to get the querystring...

For example :

Say I add a Webbrowser control on my form,

now during form load I pass
wbrowser.Navigate(new Uri("http://codeproject.com"));

Next I navigate to an article. You might invoke browser buttons to navigate. Finally to get the querystring you use :
wbrowser.Url.Query

I hope this is what you needed. Rose | [Rose]

Next time post in right section.

You have to be familiar with XSLT before you can effectively skin ASPDNSF. Trust me, I've been down that road of hell before.

Ok, here's my problem. I have two pages: one called FirstPage.aspx and the other one called SecondPage.aspx. Here's what I want to do... I start with FirstPage.aspx and here I have a button and when I click it SecondPage.aspx appears. I do that using Response.Redirect("SecondPage.aspx", false). Ok, now when it loads the second page I want to show in a label the name of the first page. How can I do that? If I have used the PostBackUrl property of the button from the first page, this would have been easy. I would have written in the SecondPage:

<br />
 protected void Page_Load(object sender, EventArgs e)<br />
        {<br />
            if (PreviousPage != null)<br />
            {<br />
                Label1.Text = PreviousPage.Title;<br />
            }<br />
<br />
        }<br />

But, I need to show the second page using Response.Redirect("SecondPage.aspx", false). So any help?

Re: Previous Page

Abhishek Sur4-Dec-09 11:55

Just pass the value using Querystring...

Do like this when you navigate to the second page:

Response.Redirect("secondpage.aspx?name=" + pagename);

After you redirect, you will find the value of name easily.

In Page_load :

protected void Page_Load(object sender, EventArgs e)
{
string firstpagename = Request.QueryString["name"];
Label1.Text = firstpagename;
}
I think this is what you needed.

<Header>
<div style="float: left; width: 100%;" class="head4">

</Header>
<Content>
<div style="float: left; width: 50%; background-color: #a9d4ff;">
<asp:Label ID="lbl_Stud_HouseholdSize" runat="server" Text="5"></asp:Label>
</div>
<div style="float: left; width: 50%; background-color: #afffaf;">
<asp:Label ID="lbl_Parent_HSize" runat="server" Text=""></asp:Label></div>
<div style="float: left; width: 50%; background-color: #a9d4ff;">
<div style="float: left; width: 100%;">

<asp:ListItem Value="1">Valid</asp:ListItem>
<asp:ListItem Value="0">Correction</asp:ListItem>

</div>
</div>
