Web Forms :: ClientScript.RegisterStartupScript Within A Class?

Mar 12, 2010

I want to use Javascript Alert to show errors and warnings to my users so I wrote a method for this purpose which is part of a class. The code is as follows:

public static void DisplayMessage(String strMessage)
{
Page currentPage = (Page)HttpContext.Current.CurrentHandler;
currentPage.ClientScript.RegisterStartupScript(currentPage.GetType(),
"AlertWindow", strMessage, true);
}

I have something like this in visual basic and it works but nothing is displayed in my C# project.
What am I doing wrong?

I have done the following in codebehind of a master page trying to use codebehind to dynamically declare a variable (TextBox1) that exists on my content page.

I don't get an error, but my value for TxtBox1 in the end is "null". I have selected onPreRender to make sure that it is the last thing to take place.

How To Use ClientScript.RegisterStartupScript

Apr 8, 2009

Is it possible to use ClientScript.RegisterStartupScript and have it execute immediately after a postback?

My situation is this: I have a button that, when clicked, creates an object. One of the methods of this object returns some values that I am trying to use ClientScript.RegisterStartupScript to pass to a JavaScript function. I can create the JS fine and when I view the source the JS is at the bottom of the page like it should be. However, I need this JS to fire when the page loads.

The ClientScriptManager seems to require a form with runat=server in order to successfully render scripts. Is everyone just doing this manually, or if dynamic support is required (to avoid registering scripts multiple times), using Placeholders?

Sometimes The Page Does Not Load Fully After An Clientscript Alert()

Mar 31, 2010

The problem i have noticed is that sometimes after a clientscript alert() the page will not post back properly and kind of "hang". The page will only show the background and will not do anything until the browser is refreshed.

[Code]....

I call clientscripts withing button click events, after the code has succeded or failed(try catch). So i will write to database/upload file/send email and then depending on the restult run a clientscript alert to notify the user. However sometimes after you "Ok" the alert the page does not finish posting back and "hangs" half loaded.

how to fix it? would adding return false; after the alert in the client script at all? (i have seen this in a online code example but they did not explain why they put it there).

AJAX :: UpdatePanel Suppressing ClientScript Action?

Aug 12, 2010

if anyone has encountered this before and knows a way to work around it? The app is ASP.NET 3.5. Some of the markup on the page in question is wrapped in an UpdatePanel, including a checkbox. The checkbox is set to AutoPostBack. When the CheckedChanged event fires, information is gathered from screen elements and dropped into a stringbuilder that becomes part of a window.open javascript that is called from this ClientScript block:

[Code]....

I put in a breakpoint and followed the execution. No errors but the javascript doesn't open the new window. Comment out the UpdatePanel and the javascript executes and the window pops up like it should. Has anyone encountered this before? Is there a way to make the UpdatePanel play nice and let the javascript execute?
