Hi,
whenever user enter text in a textbox have to disable button and if user removes text from textbox should enable button. How can we implement on client side using javascript.? I tried with onkeypress and onkeydown. but when ever I press key it is not capturing keyvalue. Can anyone help me?
pls see the below code.
function disablebutton()
{
debugger;
var prefix = 'ctl00_ContentPlaceHolder1_';
var btnRecharge = document.getElementById(prefix +'btnRecharge');
var txtpromo = document.getElementById(prefix +'txtBonusPromo');
if(txtpromo.value =='')
{
btnRecharge.disabled = false;
}
else
{
btnRecharge.disabled= true;
}
}
Thanks

This is a bad practice. Try getting the actual generated Id from the .ClientID property from codebehind.

Ok. the problem is when ever I press key first time the button is not disabled. If i enter 2nd character this time the button is disabled. the problem is it is not capturing the letter what I pressed at that moment.
The same problem occur when am trying to delete using backspace. I deleted all the characters from textbox, then button is not enabled. when I press backspace again eventhough no characters in textbox, this time button is enabling..
main problem is when ever I press key it is not capturing at that moment..
Thanks,

No change with that code also dude...

yah thanks i got it
Dim reqno As String = (CType(GridView1.Rows(e.RowIndex).Cells(1).Controls(0), TextBox).Text)

very unhelpful answer. There is no need to create a new textbox and then assign the reference to an existing textbox.

More easy solution would be copying the ajax enabled websites's web.config file to your current project and add necessary references.

I have 1000 records that i m showing in gridview.
i also implemented paging in gridview to show users 5,10,20,50 and all records per page.if user select 10 from drop down then 10 records are showing and when he clicks on next page then i fetched all the records again and show next 10 records.
How can i only fetched next 10 records,so that burden on database decreases.
Means after 10 records we should fetched 11 to 20 records only.
Can anybody provide me code to solve this problem.
Any help is greatly appreciated...

Hi
Are you having any identity column (or serial number) field in your application?
Then you need to pass extra parameters like current page number and number of records per page to your SP and based on these parameters you can return results.
-- Calculate first and last record number
<br />
<br />
SET @FirstRec = (@CurrentPageIndex - 1) * CAST(@PageSize AS INT)<br />
SET @LastRec = (@CurrentPageIndex * CAST(@PageSize AS INT) + 1)<br />
<br />
SELECT *<br />
FROM Table1<br />
WHERE IDCol > @FirstRec AND IDCol < @LastRec
If @PageSize = 10 and @CurrentPageIndex = 1, then @FirstRec will be 0 and @LastRec = 11. So first page will return only 10 records
If @PageSize = 20 and @CurrentPageIndex = 1, then @FirstRec will be 0 and @LastRec = 21. So first page will return only 20 records and so on.
Hope this solves your problems.
