You can don one thing------
LogoutLinkButton.Attributes.Add("onclick", "window.location.href =('samepage.aspx')")
if u r not save the user information in sessino variable.
if you use the user information in session variable then it's not possible.
in that case use the cookies and then use the above method and remove the user information from the cookies.

The _doPostBackWithOptions is part of the ASP.NET post back method and would normally happen.
Do you have any validation controls on this textbox? It could be the validation is failing, you need to set ValidationGroup on the inputs or you can set CausesValidation on the LinkButton to false.

Hi,
I am writing a web app in ASP.Net 2.0 and server side C#.
what i am trying to achieve is this:
multiple users work of a gridview and user A selects a row in the gridview to work with,
now when user B selects the same row while user A is still busy with that row, user B must be notified that that specific row is in use by another user.
A notify message or a row lock or anything to prevent user B from working with the same record as User A.
Does anyone have any idea how i could work around this one? 
Thanks alot
Kind Regards

Yeah, here is what I do.
First of all, here are two sql procs
<br />
create proc<br />
[dbo].[uspLockItem]<br />
(@workItemId int, @User varchar(50))<br />
as<br />
<br />
update dbo.workItems<br />
set lockedBy = @User,<br />
lockedTime = getdate()<br />
where workItemId = @workItemId<br />
<br />
<br />
<br />
create proc<br />
[dbo].[uspUnLockItems]<br />
(@User varchar(50))<br />
as<br />
<br />
update dbo.workItems<br />
set lockedBy = null,<br />
lockedTime = null<br />
where <br />
lockedBy is not null<br />
and<br />
(<br />
lockedBy = @User<br />
or datediff(minute, lockedTime, getdate()) > 20<br />
)<br />
Lock the first record when the user loads the page to work on it.
Unlock right before you get data for your grid.
On item databound method or whereever you bind your grid
<br />
LinkButton lb = (LinkButton)e.Item.FindControl("lbEdit");<br />
<br />
if (drv["lockedBy"] != DBNull.Value)<br />
{<br />
lb.Enabled = false;<br />
lb.ToolTip = "Policy locked by " + drv["lockedBy"].ToString();<br />
}<br />

Compare the value in client side.
For that you can
1. Declare a
2. Assign the server variabl'es value to the above control element using some javascript at the end of the HTML ie once the page is loaded fully..
3. Write a clientside on-click event and check textbox value. You must have onclick="return ValidateTextBoxvalue()" .... if you omitreturn statement any server side button submit the page everytime.
Thanks,

hi
can any body explain what is the difference between carriage return (\r) or you can say Enter and New Line character(\n)..
both are treated as same..
in .net(c#) if you write a file using stream writer
like this.
StreamWriter writer=new StreamWriter("c:\\test.txt");
writer.Write("Hello\r\n------\r\nHow are You.");
writer.Close();
will print this..
Hello
------
How are You.
or if you use
StreamWriter writer=new StreamWriter("c:\\test.txt");
writer.Write("Hello\r------\rHow are You.");
writer.Close();
then the results will again be same as
Hello
------
How are You.
and finally if you use like this
StreamWriter writer=new StreamWriter("c:\\test.txt");
writer.Write("Hello\n------\nHow are You.");
writer.Close();
then again the result will be same as
Hello
------
How are You.
then what is the difference between \r and \n
please explain
regards
Vishal

There are two different type of line breaks used. Unix type systems use \n while CP/M type systems use \r\n.
The \r character is carrege return (CR). It was used to move the printer head to the starting position.
The \n character is line feed (LF). It was used to feed the printing paper one line.
The CR+LF combination was used to start a new line by moving the print head and feeding the paper. This combination was kept unchanged when system arrived where a printer was no longer the only means of output.
The interpretation of these characters depend on what you use to view the file.
If you use the TYPE command in a command window to display the files, you will see that the \r version of the file will show only the last line of the file, as the cursor will return to the start of the line instead of moving on to the next line, overwriting each previous line.
The \n version of the file should really display like this:
Hello
------
How are You.
But it doesn't any more. The system nowadays interpret a single \n as a \r\n.
If you open the files in notepad, it will interpret any combination as a valid line break.
The Environment.NewLine constant contains the line break that is used on the current system.

You should output the kind of line break that the recieving system expects. That way you make sure that it will always work.
If you output the wrong type of line break it will work in some applications that are more relaxed when interpreting the text, but it may fail in other applications.

Hi guffa,
i like your Post.....
please give me reply if u have.
I am trying to do the following, it seems like it should work
Dim IE As InternetExplorer
IE = CreateObject("InternetExplorer.Application")
IE.Visible = True
Dim proxyObject As New System.Net.WebProxy("http://148.244.150.57:80/", True)
IE.Proxy = proxyObject
IE.Navigate("http://www.whatismyip.com")
basically when it goes to whatismyip.com it should show me the same address as the proxy, currently what is happening is that ie is starting up but then it sort of freezes and no page loads, any ideas how to fix this? (Also is there a way to set the proxy in the ie through vb or c#?)

Hi All
I have a page in which Paging is true. It display different records. And if records are more the it display other records on another page like 1234. There is a search technique. When I click for search, Records are found but with the following Error. Also records are not displayed on Datagrid.
System.Web.HttpException: Invalid CurrentPageIndex value. It must be >= 0 and < the PageCount
Any Help regarding this.
Thanks in Advance.

Hi
This error is displaying 'cos if you are in some other page (lets say 5th page). Then you are trying to search some other criteria. If there is no record then it should go to first page. PageCount always start from 0
So in Page Event in your code, set PageIndex = 0 before searching. Hope this solves your problem
Rate this message. Thank you. Harini

Hi frinds this is my first post. I m working with Asp .net 2 and have a problem with adding a css to the server side controls of an aspx page .Please help me .
|
|
|
|
|
You can always use any stylesheet class (CSS class) using the attribute CssClass of any server side control.
But make sure the your aspx file is having a link to the .css file.
Link to the CSS file:
======================================
add the following line with your css file name.
<head runat="server">
<title>CSS practice</title>
<link rel="Stylesheet" href="yourCssFileName.css" />
</head>
