Mouse Hover over the Grid Items causes high CPU usage

[Avi]

Hi,

I have used RadGrid with custom skins.
The problem is  if i start hovering the mouse over the grid, the CPU usage drastically

Please help me out.

The custom skin i am using is :

/* r.a.d.menu Web 2.0 skin */

.RadMenu_Blue
{
    background: url(Menu/MenuItemBackground.gif);
    border-left: solid 1px #617fb5;
}

.RadMenu_Blue_Context
{
    background: none;
    border:0;
}

.RadMenu_Blue .rmLink
{
    text-decoration: none;
    color: #fff;
    border-left: solid 1px #c2cfe3;
    border-right: solid 1px #617fb5;
    background: transparent;
}

.RadMenu_Blue .rmLink:hover,
.RadMenu_Blue .rmFocused,
.RadMenu_Blue .rmExpanded
{
    color:Black;

}

.RadMenu_Blue .rmText
{
    /*background: transparent url(Menu/RootGroupArrowDown.gif) no-repeat right center;*/
    padding-left: 22px; /* should be adjusted to the size of the images, if they are larger than 16x16px */
    margin-right: 4px;

Does this occur for every item in the Grid or is it only specific items? I noticed that you are using .RadMenu_Blue - are you using any other skins for  the RadGrid? I wasn't able to see the behavior on my side, so just making sure there's no details missing.
You could also try to see what happens (in terms of CPU usage) if you take out all hovering references in your custom skin.

Hi, Schlurk

Yes, this occurs every time.

I have used the exact css that i have posted here.


Thanks,
