Your drop down list will be rendered on the client with a name like FormViewName_DropDownList1.

Thanks - I had omitted to specify the container (FormView1). Was

DropDownList myDropDownList = (DropDownList)FindControl("DropDownList1");

but should have been

DropDownList myDropDownList = (DropDownList)FormView1.FindControl("DropDownList1");

Many thanks

How about something like this?

protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
  DropDownList myDropDownList = (sender as DropDownList);
  if (myDropDownList != null)
    Label1.Text = myDropDownList.SelectedItem.Value.ToString();
}

I have just installed the .NET Framework 1.1 on my machine. But the web application I was developing can no longer access the database I have. I keep getting the error.....

System.Data.OleDb.OleDbException: Unspecified error

Now I know it has something or other to do with permissions. And Have been messing around with every option I can find but still it doesn't want to access it.

Another strage thing it is doing, is I have a number of different .jpgs for the different webforms. And because when I upload it to my webhost it doesn't recognise the file path c:\webapplication....etc etc I simply store all the .jpgs in the root folders and just access it by Image1.jpg instead of having a path name. Right now one of my webforms beckground is blank, if I change it to Image4.Jpg it shows up, if I change it back to Image5.jpg it goes blank again, despite both files being in the root folder.

Any help would be appreciated.

It's ok I found and fixed the problem. For reference the problem was....

In the .NET Framework 1.0, ASP.NET applications use the TEMP folder that is designated by the environment variables to store temporary files. In .NET Framework 1.1, ASP.NET applications use the profile folder for the local ASPNET account to write temporary files. This profile folder is C:\Documents and Settings\ServerName\ASPNET\TEMP. The ASPNET account has permissions to write to this folder.

just point the href of your hyperlink to the document on your server's file system.

I also think the new ASP.NET 2.0 attribute configSource may be useful to you - look at the MSDN documentation: General Attributes Inherited by Section Elements[^] and see if it helps.

I am calling API of our own through dot net code to create a pdf file.After 1016 files created during report generation it's stop creating pdf files. I thing it is all because of Memory Leak. How do i force garbage colleter to release memory. I am using gc.collect() after that gc.gettotalmeory(true). How i reduces the cpu utilization it's show 100 %.

Can any one help me ?
Thanks in advance

I'm guessing the API to which you're referring is your own in-house COM object? If the memory leak is in the COM object, the .NET garbage collection won't help you, as it's not managed code.

Maybe you want to use a memory leak detector[^]?

Here's an article on CodeProject about it too -

Setting width on a table

Ista24-Apr-06 2:49

24-Apr-06 2:49

So I'm using asp.net 2.0 and I'm creating a table and I use the width property

<table width="100%">

But the compiler says I need to use a newer construct.

So where did the width go? Do i only use it in style now?

Whats up with that.

1 line of code equals many bugs. So don't write any!!

What version of (X)HTML are you using?
But yeah style="width: 100%" is nicer. And you should use layers for building the layout.

That really dosen't matter what VS you are using. You can use XHTML 1.1 with 2003 ...

But I must say that is strange becouse attribute width is perfectly valid...

Goal - is to set focus to the next textbox in a datarepeater.

Problem - I need to perform a calculation server side after the 1st textbox is changed. I can do this but turning the autopostback = "true". However when I autopostback, I need to set the focus to the next control in the row I was working on. Anyone have any ideas?

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
