anything in .NET is a solution! a solution contains one or more projects such as web project,win project, class library project etc. if you lose .sln file you can easily make a blank solution and add your existing projects to it !

Hi,

For ex, in Source's (Source.aspx) CodeBehind (C#),

string val_a="abc";<br />
string val_b="def";<br />
<br />
LinkButton.PostBackURL="Target.aspx?a=" + val_a + "&b=" + val_b;

You can get the values in Target page(Target.aspx.cs) using,

string a = Request.QueryString["a"].ToString();<br />
 string b= Request.QueryString["b"].ToString();

Also You may use PreviousPage property of ASP.NET 2.0

The following could be added to Target.aspx:

<%@ PreviousPageType VirtualPath="~/Source.aspx"  %><br />
<br />
TextBox nameBox = PreviousPage.NameBox;

Here,NameBox is the TextBox control in the Source Page.

ReportViewer Issue

The main issue is the "Select a Format" and "Size" dropdown boxes on the ReportViewer. Those controls seem to always have the highest z-order and I cannot show anything ontop of them....

- What I am trying to show ontop of them...
I cannot seem to place a <div> using absolute positioning with a table inside the <div> tags on top of those combo boxes...

- Why Would I want to do such a thing...
I am using Microsoft Visual Studio 2005 ASP.Net 2.0, ReportViewer with rendering LocalReports that show RDL Files. Showing the RDL files are working just fine with the ReportViewer but I want to have prompt options like SQL Server Reporting Service. I also have this working pretty good also.

- So Whats The Problem Again....
I searched the web for a combobox with check buttons like SQL Server Reporting services multivalue option and was unable to find one, so I made my own custom control that does nearly the same thing. My drop down is a <div> tag with a table with checkboxes. When I tell my <div> to have visibility eqaul to "visible" it show the drop down correctly on top of everyting on the page but always under the ReportViewer Comboboxes.

I have tried setting the z-order to 999999 on my <div> tag, <table> tag, and <input> tags and it is still under the report viewer comboboxes.

Please Help....

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.

javascript alert function breaks with linefeed character

#realJSOP13-Oct-06 9:00

#realJSOP

13-Oct-06 9:00

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).

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.

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.
