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?

Try:

protected void Button1_Click(object sender, EventArgs e)
   {
   if (TextBox1.Text == "something")
      {
      Response.Redirect("NewPage.aspx");
      }
   else
      {
      ....................
      }
   }

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

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.

Its may be due to the browser..!
Delete history cache and all the files in the browser and try again..!
If you still have the problem let me know..!

where is your css file..!
If it is in the root ..!then it should work
if it is in the folder lets say its in

App_Themes/Theme1/StyleSheet.css

then You have to give

background-image:url(../../images/button4.gif);

depending on the folder..!
one../ should be used..!

if you still has the problem as petr suggests open it in browser and view page source..! and check the image

Hi! I have a few problems. I have a panel and I want to implement the "mouse_over" method. I managed to implement the "mouse_click" method, because as you know asp.net doesn't provide these methods for a Panel. And also I would like to change the mouse sensitivity while my mouse is over the panel. Can anyone help me please? Any idea is appreciated..

Hi,

ASP.NET panel is rendered as DIV. See DIV element specification here: http://www.w3schools.com/tags/tag_DIV.asp[^] there is the table "Event Attributes". Onmouseover is what you are looking for.
