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

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.

I am using AJAX control toolkit Accordion control on my page.
In accordion pane i have added one pane and in that pane i put some header and content. My code below shows for header and content

<Header>
<div style="float: left; width: 100%;" class="head4">
1. Household Size</div>
</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:RadioButtonList ID="rd_Shouseholdsize" runat="server" RepeatDirection="Horizontal"
Width="70px" AutoPostBack="True" OnSelectedIndexChanged="rd_householdsize_SelectedIndexChanged">
<asp:ListItem Value="1">Valid</asp:ListItem>
<asp:ListItem Value="0">Correction</asp:ListItem>
</asp:RadioButtonList>
</div>
</div>
</Content>

The problem is when i execute, it does not show anything in pane. Just show the headers.
Any solution will be helpfull.

Here's a sample that works for me. This is one of my accordian snippets from an Ajax-enabled web project. Take a look - you might see something that you have missed. Also, check your CSS - make sure you don't have bugs in there - something that might be hiding a div for example.

<ajaxToolkit:Accordion ID="ajax_acc_Reports" runat="server"
HeaderCssClass="accordionheader" HeaderSelectedCssClass="accordionheader-selected"
SelectedIndex="-1" AutoSize="None" FadeTransitions="true" TransitionDuration="250"
FramesPerSecond="40" RequireOpenedPane="false" SuppressHeaderPostbacks="true">
<Panes>
<ajaxToolkit:AccordionPane ID="apnAnalysis" runat="server" ContentCssClass="accordionpane-selected">
<Header><strong>Analysis</strong></Header>
<Content>
<ul><li><a href="Reports/Analysis/July_09.pdf" title="QA July 09 Report"
target="_blank">QA July 09 Report</a></li></ul>
</Content>
</ajaxToolkit:AccordionPane>
</Panes>
</ajaxToolkit:Accordion>

Please let me know if this does or does not help you

PostBackUrl

Munteanu Ciprian4-Dec-09 3:13

4-Dec-09 3:13

Here's my problem: I have a button and when I click it I want to open a new page. I know that I can do this thing very easy by setting the PostBackUrl property of the button. But here's what I want to do: on my page I have a textbox and, for example when I press the button I want to test the text from the TextBox and if it's ok I want to show the new page; if not I want to display a message. I want to do that using c# language, and not JavaScript. I've tried this:

<br />
       protected void Button1_Click(object sender, EventArgs e)<br />
        {<br />
            if (TextBox1.Text == "something")<br />
                Button1.PostBackUrl = "NewPage.aspx";<br />
            else<br />
               ....................<br />
<br />
        }<br />
<br />

Ok, everithing is fine until now. But when I press the button, assuming that in my textbox I've written "something", the NewPage isn't displayed. My current page is loaded again and when I press the button again then NewPage.aspx is displayed. And I don't know why this is happening.
Can anyone help me please?

I think he wants to "Postback" to a new page and not re-direct to a new page.

Re: PostBackUrl

Mark Graham7-Dec-09 0:50

Mark Graham

The Postback url defaults to the current page and this is where your first click will return to, because, at this first click point your browser doesn't know to postback to NewPage.aspx. Only on the second click (after you've set Button1.PostBackUrl = "NewPage.aspx") will you get postback to the new page.

IF YOU NEED TO POSTBACK TO A DIFFERENT PAGE THEN....

you can't avoid using javascript. Setting PostBackUrl on the server won't affect the current request (your first click).

IF YOU'RE NOT REALLY CONCERNED WITH POSTBACK THEN....

do what the other guys suggested and replace the Button1.PostBackUrl = "NewPage.aspx" with the ReDirect, or Server.Transfer("NewPage.aspx"); code.

if i understand you correctly , when the Textbox value is equal to what you want a use to be transfered to another page else show the message(Error), if so , then you can do it this way

protected void Button1_Click(object sender, EventArgs e)
{
      if (TextBox1.Text == "something")
      {
              Response.Redirect("NewPage.aspx",false);
      }
      else
      {
        // Show your Error message here
      }
}

Hope this is what you are looking for. One more thing , Dont post the same thing twice , its not allowed here.
