Re: Accessing a javascript function from within an ascx

There is no such thing as an ascx on the client side, it's code is just part of the html that's generated. So, any script that is included in the page, you can call from the control.

IIS 6.0, ASP.NET 2.0 Web Application, and Custom Errors.

I have created a web application and have included the web.config settings pertaining to custom errors. I have turned it on and specified mapping of error pages to some HTML status codes. It works fine when I trigger the error from Visual Studio 2008, however, when deployed to an IIS 6.0 server, I tried to trigger the same errors but I got the error pages that belonged to IIS 6.0 error pages instead. I noticed some settings when I used the inetmgr to look at how I can configure IIS 6.0 not to use their custom error pages for my web application and use mine instead?

hi frnds,

I am seeing unusual memory spikes in my application. When tried to debug its due to one page where memory usage increases drastically on selection change of a drop down.

While trying debugging I could debug till Page_Prerender. But memory usage starts jumping after Page_Prerender.

there is no Page_Unload method called. what else could be running after that eating all my memory??

any thoughts?

If we need to increase the height of the dropdown list first set the font size.

ex: say 'ddlTest' is the id of the control then

ddlTest.Font.size = 20;
ddlTest.Height = 600;

is including and external vb file not allowed?

Hi,

I apologize if this is a stupid question, I'm new to asp.net. Is this code not allowed?

I don't get an error, but it seems that the code that i have in the external vb file which is inside a Page_Load sub does not execute.

Any advise would be greatly appreciated.

thanks in advance -> Frank

No, you cannot. The script tag is for client side script, it has nothing to do with what runs on the server. I recommend doing some reading on HTML, that's all this is.

Thanks for the reply. That was what I suspected, just needed confirmation. However, the script tag is not just for client side scripts, it can be used to run scripts on the server via the "runat" attribute. this is what caused my confusion since I have only used it to run client side scripts in the past, but I've seen some asp.net practices that use it to run some event handling scripts on the server side. In fact, this whole thing started when I was trying to move a script that handles the Page_Load event from within the page to an external file.

thanks again.

Uninstall Virtual Directory

I'm in the process of converting a web application from .NET 1.1 to 2.0 using VS 2005. The web app is installed using a Setup & Deployment project, which works fine. However, when the application is uninstalled the virtual directory is not deleted, only the physical directory. The virtual directory appears in IIS, but an error icon is displayed next to it when an attempt is made to view the properties. Apparently, because a physical directory no longer exists. I then have to manually delete the virtual directory. This is not an issue with the .NET 1.1 based program.

I've found a few message posts on various websites about this issue, but there are no solutions.

Any ideas?

Thanks, Paul Mac

How can I show label inside Radiobutton list ?

Hi,
Can anyone tell me how can I show label inside a RadiobuttonList . I want to show some message next to each option.

Example: 0 With login
Choose this opton if you do ..
0 Without Login
Choose this option if you do...

Continue

I can do this using Radiobutton then label then Radiobutton.... but I have to validate at server side... I want to validate at client...That's why I wanted to use previous one "RadiobuttonList".

Thanks inadvance.

You're going to have to bind to a set of strings that render the way you want, you can't use the list control AND insert something between each line. You COULD use a repeater to define a table that looks like this, that may be your best bet.

I guess it will be very complicated to user repeater to make what I want. But thanks for your reply.

It would be less complex than trying to hack a radio button list, but a lot more so than just using a radiobuttonlist, I agree.

Does mySQL have an image or blob datatype ? There are tons of articles on how this is done, although most are probably not for mySQL, the C# code would be the same.

As Christian has indicated, the short answer is yes.

The question is do you really want to do this?

Take a look at the design of the website on differently formatted height/width ratios. Sometimes a page rendered in one height/width ratio doesn't render very well when left to float at a different ratio.

I have run into this with wide screen formats where the width is considerably larger than the height. What looked good in a less radical ratio looked stretched out in a wide screen format.

It all depends on the layout and content of the website if letting the width vary unconditionally is a good design. Sometimes you may want to set the max-width CSS attribute on a block element.

Of course IE prior to IE7 doesn't recognize this attribute so you will need to implement one of those nasty IE hacks to get it to behave reasonably.

Your debugger should be helping you. Any of the following can be null.

1) Label1 (if you had missed the runat="server" in the ASP(C)X page).
2) GridView1.SelectedRow.Cells[0].FindControl("Status") returned NULL.
