Need to change "Filter" icon in grid columns

[Faisal]

Hi,
Does any one know, how can I change the "Filter" icon that comes on grid columns when filtering is enabled ?
I have tried to change it but it appears that image is displayed dynamically by kendo during grid rendering.

Thanks

In the kendo css files, they declare what to show.
Here is the rule in kendo.blueopal.min.css

.k-icon, .k-tool-icon, .k-grouping-dropclue, .k-drop-hint, .k-callout, .k-progress, .k-progress-status, .k-column-menu .k-sprite
{
    background-image: url('BlueOpal/sprite.png');
}

You should be able to create a rule in your own css to override this one.
