You need to check ValidationGroup property. Set same validation group name for your validators and submit button. Don't set any validation group for cancel button. This will solve the problem.

I have a Windows2000 based server, running many ASP.NET application. Occasionaly performance of the servers starts to degenerate enormously, and users start calling/complaining.
When I check I see the process 'aspnet.exe' taking up a huge amount of CPU.
Question now is, how do I find out which application is causing this problem?
Any suggestions?

AFAIK, there is no efficient way to find out which application is causing the problem. You can just check the event log for warnings and error messages, that might help you. Or analyze which website is getting more traffic and doing some heavy operations. That would be the one causing problem.

If you set the visibility of the file input to display:none and use a separate input button to execute the file input click event, this will open the file dialog. The returned path is then available but it is not possible to open the file directly as this would be a security vulnerability.
<script type="text/javascript">
function openFileDialog()
{
document.getElementById('myFileDialog').click();
var filePath = document.getElementById('myFileDialog').value;
alert(filePath);
return false;
}
</script>
<input id="myFileDialog" type="file" style="display:none;" />
<input type="button" value="Open File Dialog" onclick="javascript:openFileDialog();" />

I have a an asp.net web application with C# page that sends username and password to an asp.net web application with C# but different application. I need to pass these data to the asp.net we bapplication but without using the Response.Redirect method. I tried to use the HttpWepRequest and HttpWebResponse ways.I use the following code in the source page:
string strId = "1";
string strName = "amino";
//string result ="";
ASCIIEncoding encoding = new ASCIIEncoding();
string postData = "userid=" + strId;
postData += ("&username=" + strName);
byte[] data = encoding.GetBytes(postData);
// Prepare web request...
HttpWebRequest myRequest =
(HttpWebRequest)WebRequest.Create("http://localhost:1644/TragetApp/Default.aspx");
myRequest.Method = "POST";
myRequest.ContentType = "application/x-www-form-urlencoded";
myRequest.ContentLength = data.Length;
myRequest.AllowAutoRedirect = false;
Stream newStream = myRequest.GetRequestStream();
// Send the data.
newStream.Write(data, 0, data.Length);
newStream.Close();
//Response.End();
//prepare response
Stream receiveStream;
HttpWebResponse myWebResp = (HttpWebResponse)(myRequest.GetResponse());
receiveStream = myWebResp.GetResponseStream();
//result = sr.ReadToEnd();
receiveStream.Close();
in the page_load of the target page i do the following to c the username:
protected void Page_Load(object sender, EventArgs e)
{
Label1.Text = Request["username"].ToString();//.QueryString["name"].ToString();
Response.Output.WriteLine(Request["username"].ToString());
}
I put a break poit in the page_load of the target page. The username is sent correctly to the target page but after i continue running i found that the displayed page is the source page.
I need to stop at the target page after receiving the username.
What can i do?

1 - Step into code and verify your datasource is getting properly.
2 - Make sure your calling DataBind() after setting data source.
3 - Make sure your data source has values.

If you are using crystal report then format the field and customize the format and change the currency symbol.

Hi
I have an image button which has the following mouseover code in it:
onmouseover="this.src='loginbuttonover.gif'"
this works however when I put the loginbuttonover.gif in the images folder and use the following code it doesnt work:
onmouseover="this.src='~/Images/loginbuttonover.gif'"
the images folder does exist and is in the correct path
any help would be great
thanks

The ~/ syntax is used to get the root path when executed on the server side, however in this instance you are trying to execute it on the clientside where it is not understood.
This should work on the clientside:
onmouseover="this.src='Images/loginbuttonover.gif'" You can also add it on the serverside like this:
this.ImageButton1.Attributes.Add("onmouseover", "this.src='" + ResolveClientUrl("~/images/loginbuttonover.gif") + "'");

It has nothing to do with ASP.NET. You may consult your service provider. BTW , are you trying to create it using ASP.NET ?

This is not related to ASP.NET. You may like to post it in Lounge.

You may like to check out with your host if they provide some sort of control panel to manage your website.

I am using VS2008 on SQL 2005.
Forms are late bound (code behind gets the data table and serves it to the form)
Gridview questions.
1.
Is it possible to present a Gridview where 1 column (the last one) is editable by default. updates to the database will be done when the user clicks the forms Update button.
2.
Is it possible to have sub totals by groups within a Gridview.
3.
Assumes 2 is negative.
I know of 2 ways to do the sub totalling, manual HTML grids and nested gridviews in a repeater/gridview.
Why not a user control that accepts a filtered dataview for each group. I like this idea as it strikes me as more elegant than the nested solutions.
Look forward to your ideas!
Never underestimate the power of human stupidity

Yes it is possible to present a Gridview where a column is editable by default. You can use a template field to display the data in a textbox and when the form is submitted loop through the gridview rows, check for changes and update the database accordingly.
I have written an article which deals with editing individual gridview cells[^], it may also give you some ideas.
