In IE the combo box is rendered using the windows control and ignores z-order. Most menu scripts and the like find the combox box controls and hide them while they are over where the controls should be.
Using the GridView is like trying to explain to someone else how to move a third person's hands in order to tie your shoelaces for you.

I have a aps.net website where I'm trying to show an alert via javascript.
I'm setting a string variable to the following in the code-behind:
m_strAssemblyMisMatch = "<script language=\"javascript\">alert(\"" +
"This website may not function as expected due to assembly version \n" +
"mis-matches that were detected during application initialization. The \n" +
"following mis-matches were found:\n\n" +
strBadAss +
"\nPlease login and notify a support representative." +
"\");</script>";
The strBadAss variable contains text like
"\tAssemblyNameOne\n\tAssemblyNameTwo\n\tAssemblyNameThree\n" .
I'm rendering this string in the aspx page with the following statement:
<%=m_strAssemblyMisMatch%>
If I leave the linefeed characters in the string, I get a javascript error claiming there's an un-terminated string constant, and the alert dialog is NOT displayed. If I remove all of the linefeeds, the alert dialog IS displayed (with everything on one line of course).
In an attempt to see if there was indeed an un-terminated string, I tried the following:
m_strAssemblyMisMatch = "<script language=\"javascript\">alert(\"" +
"This website may not function as expected due to assembly version \n" +
"\");</script>";
Once again, if I left the linefeed in the string, it wouldn't work, but if I removed the linefeed character, it was fine.
Can anyone tell me what I'm doing wrong?

Just a guess - the newline escapes are being turned into actual newlines by the C# compiler, so by the time they make it onto the page, you now have a string spanning multiple lines (which JS doesn't like). Try double escaping the newlines (\\n).

Yeah - figured that out and came here to update my message. I hate C#.

You have to Quote the JavaScript string to make it work. As \n gets converted to a new line.
Look at the implementation of System.Web.UI.Util.QuoteJScriptString(String, Boolean) using Reflector.

Wrong answer, but thanks for responding. I had to double-backslash the linefeed character to fix it.

That is what I call Quoting. The System.Web.UI.Util.QuoteJScriptString(String, Boolean) is a general purpose function that converts everything like tab characters and special unicode characters to JS friendly form.

This is often known as escaping, which comes from the use of the escape character (0x1b) in environments like DOS and with matrix printers.
Also the term encoding is sometimes used, as in the HtmlEncode and UrlEncode methods.

On Button Postback an Aspx Page runs the following onclick C# event handler:
{
// dr[“Content”] - DataRow Item type byte[] where is a song in mp3 format
ar = dr[“Content”];
Response.ContentType=“audio/mpeg”;
Response.Clear();
Response.BufferOutput = true;
Response.BinaryWrite(ar);
Response.Flush();
}
I received error in Response.Flush() – The remote host closed the connection.(HttpException).
Please help me,
Thanks

I think you forgot the specify the length of your response. This should be equal to the size of the audio file you are sending to the client. Now the connection gets closed in the middle of the operation, because the client thinks he's done downloading the data and there's nothing left.

How can I set StreamOutput Lentgth ?, I think “al.length” was taken for “Response.Binary(al)” but maybe not. In debugger Response.OutputStream.Length is showing a SystemNotSupportedException.
Also “Response.OutputStream.Length” is readonly

Hello,
What datasource are you using for the grid? If you use a dataset paging should be supported, I'm unsure of the other sources, it sounds totally logical that IEnumerable sources don't support this kind of functionality.

1. Remove the * in the query. You are deleting records, not specific fields of records.
2. You have forgotten the apostrophes around the value you are comparing to the code field.

Are you sure? You are escaping the apostrophes in the value, is that something that you just do without knowing why, or can the value actually contain apostrophes? If it can, then you need to put apostrophes around the value.

Can't you check ContentLength property of input file ? I am guessing you should get this properrty before you upload ?
Else it is always a good idea to make use of page_error or Application_Error event to catch unknown errors.

Hmm, I think it would be even better to validate the size before even trying to upload the file. You can do this by adding a custom validator that checks the size of the file the user choose to upload with the maximum allowed size.
This provides the user with a more friendly way of saying: No, you can't upload this.

Hi,
Maximum upload size for a file is mentioned in machine.config
you can override the settings by mentining it in your project web.config
<httpRuntime executionTimeout="3600" maxRequestLength="100000"/>

Hi
I have the same problem. I spent a lot of time trying to fix this but without any success.
I added some bounded and template fields to detailsview, witch may caused the problem.
If you find a solution, can you please share it with me?
Thanks
