Don't you ask what he/she meant by "How you manage this page"?
Satish wrote: Webpage containing more than 200 controls means its processing to server everytime page requests
It's very strange. How come "Webpage containing more than 200 controls" means "its processing to server everytime page requests"? No matter how many controls you have in a particular page. If you don't submit anything then there won't be any postback..

but even if i reduced it to 5000 records the same thing is happening.
if i reduced it to 1000 records, then it gets filled in a second. but then there is no use of updatepanel and updateprogress controls.i want to fetch many records so i am using updatepanel and updateprogress controls.

But whats the purpose to fetch these much data in DropDown ?
It seem that your idea is really bad.

hi,
normally i am binding a dropdownlist inside a updatepanel. when i click the button event is fired. it shows updateprogress icon and the dropdownlist is filled. when i click the button second time it takes more time to get filled.
i observed that when i bind few thousands records to the dropdown and click the button for the second time to fill the dropdown it takes much less time. but when i increase the number of records to say above 10000 it does not hang but it takes more time to get filled on the second time when the button is clicked

I afraid, you can't.
But you can limit no. of letters using MaxLength property of the TextBox control. And you can use JavaScript to do the job on clientside.

Testbox size can be limited when its mode is "singleline" while if the the mode is multi line you use RegularExpressionValidator> i have mentioned the the re for the textarea.
<asp:RegularExpressionValidator ID="revMaxDescription" runat="server" ControlToValidate="txtDescription"
ErrorMessage="Test cannot be greater than 100 characters." ValidationExpression="(.|\n){0,100}"/>

How do I do this suggestions:
I need to take repeated input from a textbox and load it into a displayed list with a checkbox everytime add item is clicked. the GUI will look something like this. My thought was to load a repeater, but I think persistence will not allow it to work. Any suggestion or experience with this?
I'm using Asp.net 2.0 with C#
Ckbox addeditem 1
Ckbox addeditem 2
Ckbox addeditem 3
Inbut box _______________ add item

Use static DataTable or DataSet to store the values and load it when you need it.

hi,
i need to know how to register a dll via INF file - i need it so i could do it when a web page downloads a CAB.
in the CAB there will be a DLL which i want to do like regsvr32 commad does.
this is my INF for now only for registering the DLL:
[Add.Code]
Dialer=Dialer
[Dialer]
RegisterDlls = DialerRegSvr
[DialerUninstall]
UnregisterDlls = DialerRegSvr
[DialerRegSvr]
11,,MyDLL.dll, 1
if i right - click it and try to install it pops a message that sais intallation failed.
how can i do it - and would it install the dll when i will click install to the INF?
thanks,
Samy

I need to call a javascript function from within an event of the ReorderList control of the AJAXControlToolkit. It appears this is not possible in certain cases.
In particular, I need to call the 'setConfirm()' javascript function from within the ItemReorder event of the ReorderList. So, I have the following javascript at the top of my page:
[code]
function setConfirm() {
needToConfirm = true;
}
[/code]
and inside of the ItemReorder event of the ReorderList I call:
[code]
ScriptManager.RegisterStartupScript(this, this.GetType(), "setConfirm", "setConfirm()", true);
[/code]
The problem is, the javascript is never called in this scenario (I have debugged the application and the RegisterStartupScript is indeed called, it is the javascript function itself that is never called). Strangely, if I place this call inside of the ItemDataBound event (instead of the ItemReorder event), it works perfectly. Unfortunately, that solution simply doesn't work because the javascipt is called on every page load.
Does this make any sense?

Can someone please check this out for me? I've looked at the markup until I've gone cross-eyed and there is NOTHING wrong with it. Yet it works (well, looks) perfectly fine in IE but its wrong in FF, and this is a first for me.
Can someone help me shed some light on the subject?
Thanks.

Download BlogEngine.Net[^] instead, and stop the wheel re-invention in its tracks!

Its not a matter of re-inventing the wheel. Its more of a "I got inspired to write a new engine and I will be writing an article about it too" kinda thing. And it works like a charm too.
The one and only issue I have is that ONLY on the blog.aspx page it appears clunky and out of shape in FF but perfectly normal in IE.
