converting a string in to number

9-Jan-07 19:14

AJAX is used to refresh the contents of the page that is being displayed without postbacks, not to redirect to another page. To do a redirect you need to use something like Server.Redirect on the server or something like window.location on the client.

It's very complicated. Sigh | :sigh:

Int.Parse("18");

A little research, say 30 seconds, and you should have found the answer. Roll eyes | :rolleyes:

Convert.ToInt32(s);
where "s" is your string value

Try running aspnet_regiis.exe to make sure .NET has been registered with IIS.

Guys, I’m trying to debug a web page I created, based on users selection from the drop down lists, I’m changing the preferences on the page (such as background color, text, font etc). Now the problem I’m running into is that it only happens when I click the button twice. The first time button gets clicked, nothing happens but there is a post back to itself. When I try to debug it by setting break points, I see that when the control gets returned back to the browser and I click the submit button after selecting the properties from the drop down lists, it goes through the code for the event handler (btn_Click()) and then when it reaches the end, it comes back to the top of the event handler (btn_Click())
and goes through the code again. When it finish executing it again, VS.Net (2003 ) opens up an error message box saying there is no more source code to execute and that DO YOU want to see the disassembled code. I’m not quite understanding why is it happening? BTW I’m using cookies to store the values from the drop down so I can use them on subsequent pages. Also I’m using inline styles sheets and in aspx changing the properties of body and table elements for instance. But that still doesn’t explain why it needs the button clicked twice??? Can someone please explain? The code is shown below:

<br />
<br />
private void Page_Load(object sender, System.EventArgs e)<br />
		{<br />
			if (!IsPostBack)<br />
			{<br />
				HttpCookie cookie = Request.Cookies["preferences1"];<br />
				ViewState["Referer"] = Request.Headers["Referer"];<br />
          <br />
				if ( cookie != null )<br />
				{<br />
					BackColor.SelectedItem.Value = (string)cookie.Values["BackColor"];<br />
					ForeColor.SelectedItem.Value = (string)cookie.Values["ForeColor"];<br />
					FontSize.SelectedItem.Value = (string)cookie.Values["FontSize"];<br />
					FontName.SelectedItem.Value = (string)cookie.Values["FontName"];<br />
					NavControl.SelectedItem.Value = (string)cookie.Values["NavControl"];<br />
				}<br />
			}<br />
			globalNav2.Visible = false;<br />
		}<br />
<br />
<br />
<br />
		public void btnSubmit_Click(object sender, System.EventArgs e)<br />
		{<br />
				//HttpCookie cookie = Request.Cookies["preferences1"];<br />
<br />
				HttpCookie cookie = new HttpCookie("preferences1");<br />
<br />
// where ForeColor, BackColor and others are just the IDs of the Drop down lists.<br />
<br />
				cookie.Values.Add("ForeColor",ForeColor.SelectedItem.Value);<br />
				cookie.Values.Add("BackColor",BackColor.SelectedItem.Value);<br />
				cookie.Values.Add("FontSize",FontSize.SelectedItem.Value);<br />
				cookie.Values.Add("FontName",FontName.SelectedItem.Value);<br />
				cookie.Values.Add("NavControl",NavControl.SelectedItem.Value);<br />
<br />
				Response.AppendCookie(cookie);<br />
			<br />
					}<br />
<br />

}

Write the above code in a separate function and call it in Button_Click Event.

The problem is because,
The Page_Load Event is called first than the Button_Click Event eventhough you clicked the button.

I am sure your problem will be solved.. Have a great day...

Hi Venkatesh, thanks for your response. I see your point from code reusability and conciseness point of view, but I can't understand how extracting that code, and calling a function instead that will execute the same code from the same location would solve this problem. I mean are you saying that code in Page_Load needs to execute at the time of button click (menaing when the code for the button click event handler is executed).

Venkatesh, could you please help me out here! BTW the code sample that I am following is on http://samples.gotdotnet.com/quickstart/util/srcview.aspx?path=/quickstart/aspplus/samples/apps/cookies1/cookies1.src[^]. They are using two pages, I wonder if that has to do with that second click?
Please help.
Thanks

Ignore what he said, it makes no sense at all, even from a code reuse point of view.

Of course the Page_load event is fired before the Button_Click event but moving the code you indicated into a seperate method will have no effect. Notice that it has been placed inside the if(!IsPostBack). Since the button click, or dropdown event is a postback the code will be not be executed and so is not the problem. Also notice that it appears to be setting the selected value of the dropdowns based on the value in the cookie. Calling it from the button click event would do nothing more than reset the dropdown lists.

Are the dropdown lists set to autopostback?

Although it doesn't solve your problem directly, if you need to have values available on multiple pages then there are better ways to store them, such session or cache. Using cookies is fine if you want the data persisted on the client and available for other sessions.

Hi Mark, thanks for the response. No they are not set to Autopostback = true, since there are more than one property settings that a user can select from the drop downs (if you get a chance, please look at the link I mentioned in the prior post....that's pretty much the same code (as far as the cookies) I'm using. Also they are using two pages to demonstrate that... and if you run the sample from http://samples.gotdotnet.com/quickstart/aspplus/doc/stateoverview.aspx[^] scroll all the way down to client side cookies...you would know what I'm talking about??? It just really weird? Any ideas???

Thanks

Sorry without seeing your complete code sample I don't see any reason off hand why you would be getting two events for the button click. If you are following the sample you pointed to it should work fine.
