The only way to let your code behind know that the window was closed, is an AJAX call.

No, it can't be done. As someone has shown already, you can call javascript on a page close. Only AJAX can call the server.

Not sure if the answers you have got will help - you can't call javascript in your code behind. You can emit javascript as part of the html you send to the client to force a method to run when the page is rendered. But, js only runs on the client.

Sandeep Akhare15-Oct-07 23:32

15-Oct-07 23:32

How can you use javscript function in code behind only thing that you can do in code behind is you can register javascript for perticular control
i thing there is some misunderstanding .

I percieve that English is not your first language, so I will be polite. You've been told the only possible answer, and belligerently asking over and over is not going to change the way every browser in the world works, or the nature of HTTP, to contrive to create the answer you're trying to find. AJAX is your only option.

I know that I can not call javascript in code behind file. but i use javascript in content place holder. just call in code behind file.

It is not a good practice to call the Javascript function in the codebehind file.

Just put the javascript in the content place holder and call it.

How to use authentication in web.config without type all username and password within <credentails> tag?

I don't need this...

<br />
<br />
...<br />
< credentials ><br />
  < user name="AAA" password="BBB" ><br />
  ...<br />
< /credentials ><br />
...<br />
<br />

Because of i have MySql database which stored username and password.
For LogIn.aspx code like this

protected void Login1_Authenticate(object sender, AuthenticateEventArgs e)
    {
        if (CheckAuthenticate(Login1.UserName, Login1.Password))
        {
            e.Authenticated = true;
            Response.Redirect("index.aspx");
        }
        else
        {
            e.Authenticated = false;
        }
        
    }

...
 public bool CheckAuthenticate(string user, string pass)
 {
     //My authentication checking logic
     //Query username and password from database for comparison with user  
     //and pass agument
 }

I've google it to find some tutorial but it's not help.

How to do this?
thank =)

web user control problem

Sonia Gupta15-Oct-07 21:39

15-Oct-07 21:39

I have following things in my web project
1. A web user control which contains a drop downlist.
2. A web-form that contains a drop-downlist and the web contol above mentioned.
3. Two tables - One is master and other is child.
I am populating the the dropdownlist which is lying in the web-user control with the master table data.
Now my question is , How can i populate the dropdownlist , which is lying in the web-form from the dropdownlist , which is lying the web-user control , on the selected index changed function of the drop-downlist lying in the web-user control.

By subscribing to the selection changed event in the main form which contains the user control. Or by using a delegate to let the main form know that selection has changed in the control.

However, if they are tied together to that degree, odds are the control is poorly designed.

At what point do you intend to learn to use google, or to buy a book ?

The control itself defines an event, so the easiest thing ( although not the nicest ) is to expose the control publically. There's no point using a get accessor, it's a reference, once someone can get the control, they can change it's properties. Then hook up the selectonchanged event in the main form.

I think in your application the meaning of user control is changed
why you have created a user control if there are so much dependencies on that control. I think it should not be a user control

Hi,

I have the following wizard control that I am not getting to work:

<asp:Wizard
ID="wizInsertAddress"
CancelDestinationPageUrl="Default.aspx"
DisplaySideBar="false"
NavigationStyle-HorizontalAlign="Left"
Width="100%"
runat="server"
OnFinishButtonClick="wizInsertAddress_FinishButtonClick">

<StartNavigationTemplate>
<asp:Panel ID="pnlStartNavigation" Style="padding:0px" Runat="Server">
<asp:Button ID="btnStartNext" Text="Insert" CommandName="MoveNext" runat="server" />
<asp:Button ID="btnCancel" Text="Cancel" Runat="Server"/>
</asp:Panel>
</StartNavigationTemplate>
<WizardSteps>
<asp:WizardStep ID="wizStep1" Title="Start" StepType="Start" Runat="Server">
...here I have input controls...
</asp:WizardStep>
<asp:WizardStep id="wizStep2" Title="Complete" StepType="Complete" Runat="Server">
<asp:Literal ID="litSuccessMsg" runat="server" />
<div class="verticalSpacer10"></div>
<ul class="actionlist">
<li><asp:HyperLink ID="hlUserDetails" runat="server" /></li>
<li><a href="Default.aspx">Users Home</a></li>
</ul>
</asp:WizardStep>
</WizardSteps>
</asp:Wizard>

Basically the first step is to capture address details, and then when the Insert button is clicked it goes to step 2 and displays a success message. Now in my wizInsertAddress_FinishButtonClick I do a simple Response.Write("in wizInsertAddress_FinishButtonClick"); to see if the method is fired. But it is not!!

Please can someone explain why??

Thanks
