Generally the implementation is to rebind the grid on page change that leads to loss of any selection made.
If you want to persist selection across various pages, you need to maintain the selection somewhere or use client side pagination avoiding rebind on page change. Following article demonstrates one of the ways to handle it: Maintaining States of Selected CheckBoxes in Different Pages inside the GridView[^]

If i have to give an opinion,i'll say that use javascript to store the value corresponding to the question no and show that everytime. By default keep nothing in the radiobutton.
Hope this helps.

I'm trying to implement the sync solution using Microsoft Sync Framework. The server will be SQL server database contains the documents in FileStream and client will be the File system (Windows OS).Do anybody have any idea on this. My application scenario is :The database server contains the File/Documents in the form of byte array by the FileStream mechanism from SQL server. And the Sync activity will syncronize the documents from SQL server to any given file system. Please help me out.
Regards

And the issue is?
Here is what is expected of enquirers:
1. TRY first what you want to do! You may find that it's not that hard.
2. Formulate what was done by you that looks like an issue/not working.

help me int his..,
<script type="text/javascript">
function isCapslock(e) {
e = (e) ? e : window.event;
var charCode = false;
if (e.which) {
charCode = e.which;
} else if (e.keyCode) {
charCode = e.keyCode;
}
var shifton = false;
if (e.shiftKey) {
shifton = e.shiftKey;
} else if (e.modifiers) {
shifton = !!(e.modifiers & 4);
}
if (charCode >= 97 && charCode <= 122 && shifton) {
return true;
}
if (charCode >= 65 && charCode <= 90 && !shifton) {
return true;
}
alert("CpasOn");
//return false;
}
</script>
<asp:TextBox ID="Password" runat="server" TextMode="Password" Width="150px" onkeypress="return isCapslock(this)"
></asp:TextBox>
if i press caps lock button nor not it gives me the message Capslock is on...,?

There's a blog post here ^[^] that claims to detect Caps Lock, but I haven't tried it.
Personally I like this solution[^] which just checks if the character entered is in Caps. If it is, and the ShiftKey is pressed, then Caps Lock is probably on
var s = String.fromCharCode(e.which);
if ( s.toUpperCase() === s && s.toLowerCase() !== s && !e.shiftKey ) {
alert('caps is on');
}

Hello Everybody, I want to develop an asp.net application.
I want to layer it in such a way that the data layer, data access layer and Business Logic Layer are designed in such a way that these layers could be used for any application UI such as silver light, windows apps, WPF ,android apps and ipad apps.
To achieve this I was planning to develop the BL layer using restful services and WCF.
BL layer will be the one interacting with the UI. I have seen lots of debates on this. I feel what I am planning is correct but the application will be huge around 3000 or more web pages and around 1000 table, I want to feel confident I am not going on a wrong track.
Any suggestion and advice will be appreciated.
Regards

@entry_date varchar(20),
@updated_date varchar(20),
@status varchar(20),
@cno varchar(20),
@eno varchar(20))
as
declare @SQL varchar(max)
set @SQL='SELECT * FROM anu123 where 1=1 '
if (@status='ALL')
begin
set @status='ALL'
end
if (@status='A')
begin
set @status='A'
end
if (@status='R')
begin
set @status='R'
end
if (@status='D')

set @entry_date =CONVERT (datetime, @entry_date, 103)
set @updated_date= CONVERT(datetime, @updated_date, 103)
set @SQL=@SQL+'and entry_date>=''' +@entry_date+'''and updated_date<='''+@updated_date+''''
end
if (@cno<>'')
begin
set @cno=@cno
set @SQL=@SQL+'and cno=''' +@cno
end
if (@eno<>'')
begin
set @eno=@eno
set @SQL=@SQL+'and eno=''' +@eno
end
exec (@SQL)
End
Can anyone tell me,where am wrong? stuck from 2 hr. Saying incorrect syntax near the last end

alter procedure mdi_anu
(
@entry_date varchar(20),
@updated_date varchar(20),
@status varchar(20),
@cno varchar(20),
@eno varchar(20)
)
as
begin
declare @SQL varchar(max)
set @SQL='SELECT * FROM anu123 where 1=1 '
--if (@status='ALL')
-- begin
-- set @status='ALL'
-- set @SQL=@SQL + 'and status=''' +@status
--end
if (@status='A')
begin
set @status='A'
--set @SQL=@SQL+' and status='''+@status
end
if (@status='R')
begin
set @status='R'
set @SQL=@SQL+' and status=''' +@status
end
if (@status='D')

end

end
if (@eno<>'')
begin
set @eno=@eno
set @SQL=@SQL+'and eno=''' +@eno+
end
exec (@SQL)
end
the error which m getting is that,suppose m choosing 'D' as my input in the status i get
"Unclosed quotation mark after the character string 'D'.
Incorrect syntax near 'D'."
Whats the problem?
|
|
|
|

May be you should append a single quotes after +@status in all your if conditions, if it a varchar field?
|
|
|
|
|
Include a space before and after every string. For example instead of writing 'and eno=''' write ' and eno='' '
Hope it helps. If it does not instead of exec(@SQL) in your SP write print(@SQL) and you will have the complete SQL Query. That will clear the picture to a good deal where the error is.
