  • CSS sliding doors technique for buttons, IE8 problem

    - by Kelvin
    Hello All! I used sliding doors technique, explained here: http://www.oscaralexander.com/tutorials/how-to-make-sexy-buttons-with-css.html With only one exception, that I decided to add one more image for "hover" effect. My code works well for all browsers, except IE8 (and maybe earlier versions). a.submit-button:active and a.submit-button:active span are simply blocked by "hover" and never work. Does anyone knows solution for this? Thanks a lot in advance! <style type="text/css"> .clear { /* generic container (i.e. div) for floating buttons */ overflow: hidden; width: 100%; } a.submit-button { background: transparent url('images/button-1b.png') no-repeat scroll top right; color: #fff; display: block; float: left; font: bold 13px sans-serif, arial; height: 28px; margin-right: 6px; padding-right: 18px; /* sliding doors padding */ text-decoration: none; outline: none; } a.submit-button span { background: transparent url('images/button-1a.png') no-repeat; display: block; line-height: 14px; padding: 6px 0 8px 24px; } a.submit-button:hover { background-position: right -28px; outline: none; /* hide dotted outline in Firefox */ color: #fff; } a.submit-button:hover span { background-position: 0px -28px; } a.submit-button:active { background-position: right -56px; color: #e5e5e5; outline: none; } a.submit-button:active span { background-position: 0px -56px; padding: 7px 0 7px 24px; /* push text down 1px */ } </style> And this is the button: <div class="clear"> <a class="submit-button" href="#" onclick="this.blur();"><span>Hello All</span></a> </div>

  • Why can’t GridView extract child control’s values directly?

    - by SourceC
    Hello using Bind in a GridView control template enables the control to extract values from child controls in the template and pass them to the data source control. The data source control in turn performs the appropriate command for the database. For this reason, the Bind function is used inside the EditItemTemplate or InsertItemTemplate of a data-bound control. Why is Bind() needed to extract values and pass them to GridView. Why isn’t GridView able to extract child control’s values directly? thanx
