<blockquote class="FQ"><div class="FQA">sindhutiwari wrote:</div>fuction in java script ..square()</blockquote>
why you calling a java script function for Squre.
if both of your Control are server side then do it in server side.
I think you want to calculate the Squre of tb1.
So do one thing in client side read the ClientID of the control (Tb1) and calculate the squre of Tb1.
and on lostfocus of TB2 Register one ScriptSetupBlock for calling the funciton .
Try the steps... Hope you learn a lot for doing this.
if any problem ask me !!!!
Best Regards

Tb1.Attributes.Add("OnBlur","YourJsFunction();"); call this in page_load. Inside JS function, find the element and put value to the second text box.

Attributes.Add adds attribute to the rendered controls. OnBlur is the JS event fired when it lost the focus.

These all are very basic and I don't think that there would be a step by step tutorial for this. You may check this[^] MSDN article or getting some information.

HI,
Can we add 2 datatables in one dataset, each datatable from different database. If so, how we can add at a time.
Suppose if i get the datatable using sqlserver database then
dataset1 = sqldataset.tables[0];
If i get the datatable from Oracle database then
dataset1 = oradataset.tables[0];
is it correct? if so, it doesn't overwrite?

DataSet ds = new DataSet();<br />
ds.Tables.Add(dataTable1);
ds.Tables.Add(dataTable2);
Thanks,

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?

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"?
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..

Hi,
I think its really a very bad idea to bind these many records to Dropdown...

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,
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
