Making Asp.net web page rendered in IE8 to work similar in IE7

vnsblog — Wed, 14 Oct 2009 11:57:30 +0000

Hello All,

After the release of different versions of IE browsers, it is always a fret for the web developers on compatibility issues. Even I was experiencing the same kind of obscurity in one of my recent projects. So I did some ground work on it and got some useful information to embark upon dealing with IE 8 compatibility issues.

Let’s get the scenario straight away,

If your asp.net web application is working fine with IE 6 & IE 7. But if you want to let the clients benefit the same functionality with IE 8 browser then you need to just do a little stuff and there are two ways of doing it.

Go to the IIS and spot on your website, add a HttpHeader with HeaderName as ‘X-UA-Compatible’ and value as ‘IE=EmulateIE7’

Add the below meta tag within the tags on all the pages in your application.

Based on your expediency you can opt for either of the one.

Also another small tip for developers who tend to develop applications targeted to multiple browsers,

Always for setting the height and width of the html elements always use

Style=”height:20px;width:20px” instead of using values directly in the height and width attribute of the html element.

For example:

Use

Instead of

–Problem shrinks to half, if the cause is identified

Wrapping text in GridView cell

vnsblog — Wed, 07 Oct 2009 10:48:27 +0000

Hi,

In order to wrap cell text in a gridview use

, it works fine until the cell text contains spaces, like ‘grid view cell text’. But it fails and the grid expands its width if the cell text is lengthy and continuous like ‘aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa’

This can be resolved by using page level inline CSS

declare a style for a TD since the rendered grid cell will be TD.

In the grid view set the attribute to RowStyle-CssClass=”WrapStyle”. I have tested it with IE and works fine.

Happy coding!!

Formatting numbers in C#

vnsblog — Wed, 07 Oct 2009 10:20:06 +0000

Hello all,

This is my first blog ever. So I thought of starting it with a simple .net programming tip.

Number formatting in C# can be done as below,

string.Format(“{0:#,###}”, 1000000);

output will be -> 1,000,000, but when the value to be formatted is zero then formatted output will be an empty string. In this case use the format as below to get 0 as formatted output.

string.Format(“{0:#,###0}”, 0);

For decimals use

string.Format(“{0:#,###0.00}”, 0);
