Have u gone through the link given by Apurva Kaushal?
After 30 min, the Session has expired. It works fine & Correct.
Dont confused about Client Side or Server side. If you are using 'Cookies', the Cookie will retain its session values only 30 min (Cookie is stored in Client system only). This 30 min given in 'SlidingExpiration' attribute.
Cookie is expired after 30 min., the time the last request was received.
U know web is stateless. The server understands the Request from single user (Browser) by Session ID only.After the Cookie expires, for example, if u submit the Web Page, then the server cant able to idetify you (Session ID expired).So it gives "session expired" warning. You need to login again.
Have got it !!

Jay

If you are having problem in handling it directly then use onitemdatabound event for that purpose.
Or Here[^] you will get lots of stuff on gridview control.

Hi all!
How can I apply CSS to the browse button of FileUpload Control? Can I also add onmouseover and onmouseout properties to the button?
If not, is there a function or method that has the same functionality as the FileUpload? like I can just invoke it on button click? My codebehind language is VB.
Thanks alot.

Sounds like you are not recreating your control on the selectedIndexChanged post back event.
When you create it like this in a button click, it is not persisted in the page's control tree.

<%
mysql=("select MAX(cast(SUBSTRING(Appellant_Notice_Number,1,LEN(Appellant_Notice_Number)-5)as int))+1 As vals FROM RegisteredCase where Appellant_Notice_Number is not null")
set rs=con.execute(mysql)
yearvar=year(Date)
if(isNull(rs("vals"))) then
anum="1/"& yearvar
else
anum=rs.fields("vals")&"/"& yearvar
end if
%>
I get the following error in the above code. Plz help me solving this error.
(Note: Appellant_Notice_Number values are, for example 225/2005 or 1/2006 or 15/2005 etc)
Microsoft OLE DB Provider for SQL Server error '80040e14'
Invalid length parameter passed to the substring function.

LEN(Appellant_Notice_Number)-5
My guess would be that this bit is returning a negative number...that's what usually causes that error....
Or a zero-length string perhaps?

hi guys pls help me wit this code below:
comm.CommandText = "select BrandID, Brand, ('Logo_Pics/'+BrandLogo) as BrandLogoFile from Brand";
SqlDataReader dr = comm.ExecuteReader();
DataList1.DataSource = dr;
DataList1.DataBind();
dr.Close();
this code is working fine which is to show the picture of the products into the datalist1.
now i am trying to make it so that when users click on the picture it would link them to another page.
does any one have any knowledge of this this pls share your ideas and views pls.

I dont know, what control u have used in DataList to display the Picture of the product.
You may use 'ImageButton' control for ur purpose & may use PostBackUrl property for navigating to another page on Clicking the Image.

Jay

Hi,
I think you have used DataList control here, I am not familier with DataList, we actually use Data Repeater, the procedure to set the link is in data repeater:
<asp:repeater id="Repeater1" runat="server">
<itemtemplate>
" border="0" />
Sorry i want to suggest you, but i cant able to answer you correctly...............
bye

Couple of ways to do this - simplest is to add an on click handler to each image in ItemDatabound....

I have a problem caused by an earlier design of a program developed by an external vendor. We have an sms system that accepts request via URL parameters (Eg: http://internalserver/sms.aspx?hp=3453453+msg=testtest).
I am trying to make this a more user friendly experience and thus have came out with a webform that accepts a mobile number and the message. Whenever the user clicks on the "Send" button, I would do the followng:
1) Create the URL and initialise it accordingly. Eg: http://internalserver/sms.aspx?hp=3453453+msg=usersmessage
2) The webpage will then launch this url in a new browser window.
The problem is if a user would like to send multiple sms, a large number of new browser window will open which is not ideal. Is there a way in ASP.NET to execute a url without having to launch another browser window or redirect the current one.
Note: The earlier system cannot be changed.

|
|
|
Server.Execute(url, StringWriter);
You can than use StringWriter's ToString() method to get the generated HTML.

I need to convert the following code into .net. the existing code is in coldfusion and runs as a background process.
Can someone help me in converting this coldfusion code to .net code.
<code>
<CFPARAM NAME="ATTRIBUTES.JUSTIFY" DEFAULT="no">
<CFIF NOT ThisTag.HasEndTag>
<CFABORT SHOWERROR="You need to supply a closing <CF_FileWriteText> tag.">
</CFIF>
<CFIF ThisTag.ExecutionMode is "End">
<!--- If it has <pre> or <code> tags, just leave the whole page alone!! --->
<!--- When CF reg expressions have non-greedy searching, I'll deal with this more intelligently --->
<CFIF REFindNoCase("<pre>|<code>", ThisTag.GeneratedContent) EQ 0>
<!--- Replace whitespace between CR/LFs with a single CF/LF --->
<!--- That fixes almost all of the major whitespace --->
<CFSET ThisTag.GeneratedContent = REReplace(ThisTag.GeneratedContent, "[#Chr(13)##Chr(10)#]+[[:space:]]*[#Chr(13)##Chr(10)#]+", "#Chr(13)##Chr(10)#", "ALL")>
<!--- If JUSTIFYing, remove whitespace at beginning of each line --->
<CFSET ATTRIBUTES.JUSTIFY = ucase(ATTRIBUTES.JUSTIFY)>
<CFIF ATTRIBUTES.JUSTIFY EQ "Y" OR ATTRIBUTES.JUSTIFY EQ "YES">
<CFSET ThisTag.GeneratedContent = REReplace(ThisTag.GeneratedContent, "[#Chr(13)##Chr(10)#][[:space:]]*", "#Chr(13)##Chr(10)#", "ALL")>
</CFIF>
</CFIF>
</CFIF>
<CFSETTING ENABLECFOUTPUTONLY="NO">
</code>
Thank you in advance.

+ "Help" is a useless title, see Chris's golden rules[^].
