C# – Response.Redirect in .NET 4.0

asp.netcnet

Response.Redirect() no longer working when upgrade the application to ASP.NET 4.0

Response.Redirect() is used inside Update panel
and we using the AjaxToolKit 4.0

it gives me the error:

Error: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the
server could not be parsed. Common causes for this error are when the response is
modified by calls to Response.Write(), response filters, HttpModules, or server trace is
enabled.

you have to do this

string redirectURL=(a proper url goes here)

string script = "window.location='" + redirectURL + "';";

ScriptManager.RegisterStartupScript(this, typeof(Page), "RedirectTo", script, true);

.net – Difference between decimal, float and double in .NET

float and double are floating binary point types. In other words, they represent a number like this:

10001.10010110011

The binary number and the location of the binary point are both encoded within the value.

decimal is a floating decimal point type. In other words, they represent a number like this:

12345.65789

Again, the number and the location of the decimal point are both encoded within the value – that's what makes decimal still a floating point type instead of a fixed point type.

The important thing to note is that humans are used to representing non-integers in a decimal form, and expect exact results in decimal representations; not all decimal numbers are exactly representable in binary floating point – 0.1, for example – so if you use a binary floating point value you'll actually get an approximation to 0.1. You'll still get approximations when using a floating decimal point as well – the result of dividing 1 by 3 can't be exactly represented, for example.

As for what to use when:

For values which are "naturally exact decimals" it's good to use decimal. This is usually suitable for any concepts invented by humans: financial values are the most obvious example, but there are others too. Consider the score given to divers or ice skaters, for example.
For values which are more artefacts of nature which can't really be measured exactly anyway, float/double are more appropriate. For example, scientific data would usually be represented in this form. Here, the original values won't be "decimally accurate" to start with, so it's not important for the expected results to maintain the "decimal accuracy". Floating binary point types are much faster to work with than decimals.

You might be using response.write, server.transfer or similar within updatepanel; avoid that.
