The short answer is: you can't.
Richard's trick is a good one, and will overwrite the default context menu that appears from a right-click on the page. However, the browser is considered to be owned exclusively by the user, not the page. As a result, no code on a page can interfere with the core functions of the browser. The "View-->Source" option of the browser's main menu bar will always be present. Also, a user can simply disable javascript (or use an add-on) to use the default context menu despite any scripting that you do to hide it.
At the end of the day, anything that you render to the browser can be viewed as source and there is nothing that you can do to prevent it. As a rule of thumb, I'd strongly recommend that you render nothing to the browser that you do not wish the general public to see.

Have you tried starting the web server?
|
|
|
|

But seriously. Is there a web server installed on your machine?
To check if IIS is there, click start > run > type inetmgr and hit enter. This should open up IIS admin page if it exists.

Man, try adding a new virtual directory within IIS and pointing it at your website files, or possibly re-installing the app if you're still getting issues.

Hi all,
Im using C# as my code behind, im having a code in the button click event where im checking whether a file is exists, if it exists then it show the confirmation message box like "file found, want to continue", but its happening if we register the script in the page load and its not checking the condition. By clciking the button itself its showing the message box.
i need that script should get pop up only after the condition get satisfied. Is it possible? Please help me out to solve this problem. Thanks a lot in advance.
The code is given below
private void Page_Load(object sender, System.EventArgs e)
{
i = "file Exists";
StringBuilder str = new StringBuilder();
str.Append("");
str.Append("function PopWindow()");
str.Append("{");
str.Append("alert('hello world')");
str.Append("}");
str.Append("");
if(!Page.IsClientScriptBlockRegistered("clientscript"))
{
Page.RegisterStartupScript("clientscript",str.ToString());
}
Button1.Attributes.Add("onclick","PopWindow();");
}
private void Button1_Click(object sender, System.EventArgs e)
{
if (i=="file Exists")
{
int x= 0;
int y =0;
x = x+ y;
Button1.Attributes.Add("onclick","PopWindow();");
int a = 2;
int z = 2;
z = z+ a;
Response.Write(z.ToString());
}
}
Regards
Mukilan.

Well the problem is that client side code always get executed before the page is sent to the server.
So if your button has a server-side event and also a client side one (Button1.Attributes.Add("onclick","PopWindow();"); ) the PopWindow() will get called when you press the button and after that the page will be send to the server.
What you need to do is register the client script to be shown after the page has been submitted. So do not add an onclick attribute to the button, but in the Button1_Click(object sender, System.EventArgs e) method after validating if you need to show a popup just use Page.RegisterClientScriptBlock("msg","PopWindow(););. This will cause the PopWindow javascript method to be called after the page loads on the clients side.

thank u very much for your suggestion
but if i register code after checking the condition, that message box is not getting pop upped, in the browser if we click button, the "popwindow()" string is getting displayed
Code is given below,
private void Button1_Click(object sender, System.EventArgs e)
{
if (i=="file Exists")
{
int x= 0;
int y =0;
x = x+ y;
StringBuilder str = new StringBuilder();
str.Append("");
str.Append("function PopWindow()");
str.Append("{");
str.Append("alert('hello world')");
str.Append("}");
str.Append(""); Page.RegisterClientScriptBlock("clientscript","PopWindow();");// Here is the problem
Another Way
Page.RegisterClientScriptBlock("clientscript",PopWindow()); // its giving build error as follows(without specified in the quotes)
c:\inetpub\wwwroot\WebApplication1\WebForm1.aspx.cs(79): The name 'PopWindow' does not exist in the class or namespace 'WebApplication1.WebForm1'
int a = 2;
int z = 2;
z = z+ a;
}
}

Why are you dynamically creating the PopWindow function. Surely if it's static you can just include it in the head of the page?

You are only putting the code for the function in the StringBuilder, you don't use it for anything.
The StringBuilder doesn't automatically recognise that you have created a script, and that there is a web page where the script could go. Neither does the RegisterClientScriptBlock automatically recognise that you happen to have a StringBuilder that contains a script with a function that corresponds with the function call in the code that you do add to the page.

The problem is that you don't have any function called PopWindow() in your rendered page. Why? Because you didn't place it there. You have just defined the StringBuilder in you method, but didn't send it to the page.
1. Put the Javascript in a .js file and inlcude a link to it from HTML
or
2. Register the javascript in the page on page_load just as you do the function call.

 I create DataTable in code C# as Add-method of DataRow. Then I do DataGrid.DataSource = DataTable and DataGrid.DataBind.
Can I set BackColor for DataRow at moment of work Add-method? It is impossible to set BackColor for object DataGridItem in DataGrid in my situation.

Hi there,
You can use the XSLT to transform an XML document to a word document in xml format. Basically, you need to understand the XML schema[^] for a Word document, then you can produce an XSL stylesheet to transform the xml file.

Hi,
Are there any tab controls in ASP.NET 2.0?? If so what is it called because I can't find it.

Not that I know of. But you can emulate a tab control by using a table and showing/hiding rows using style display:none; and display:""
