HI,

Recently i faced this question in one of the interview. i need solution for this.

Question is :---

If you have webpage and have a requirement to add more than 200 controls like labels, textboxes, dropdownlists etc.....How you manage this page.
Webpage containing more than 200 controls means its processing to server everytime page requests. How you manage this page?

G. Satish

Instead of server controls i preferd to use HTML controls, becoz it does not required parsing of ASp.net control tags to HTML tags which saves lot of processing n time.

So, you are going to write the code in Javascript?

Don't you ask what he/she meant by "How you manage this page"?

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..

Hi,
I think its really a very bad idea to bind these many records to Dropdown...
Whats yr purpose to bind to Dropdown ?
You wanna give user selection from these many records ?
Its really bad.

Confused | :confused:

Thanks,

To get something you must have to try once.

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.

Hi,
There will not be any effect using update panel in that.
But whats the purpose to fetch these much data in DropDown ?
It seem that your idea is really bad.

Hi,
actually, i have got a page. when a user selects a records in a drop down and then he clicks a submit button. after clicking the button the page takes times to process and then it transfers to the next page. before tansfering, the selection page is getting displayed and i dont want the user to click the button again. so i am showing the updateprogress icon till the process gets complete.

Thanks

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 am using server.transfer to take data from one page to the other. I have bunch of text boxes with data and I am transfering to a new page with server.transfer. The problem is I am having a sum textbox in the first page, the contents of which i don't want to transfer. Anybody can help me how to do it..

Raj D

You put that sum in the Session variable. and get this value at the end...

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}"/>

private string ToSentenceCase(Match match)
{
return match.Value[0].ToString().ToUpper() +
match.Value.Substring(1);
}

string text = Regex.Replace(TextBox.Text, @"\w+", ToSentenceCase);

and in return function wat i have to send

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?

Samy
