Add Images in place of expander in RadTreeView C#

[Ruchit]

Hello Friends,

I am planning to add images in place of the expanders which are present in the RadTreeView control.

I want to accomplish my task using C#.

Any help would be appreciated.
Thanks.


Best Regards,

Hello Ruchit,

In order to change the image , you should change the CSS class of the span where the image is rendered. There are two classes :rtMinus and rtPlus, the first one represents the collapsed node and the second one the node when it's expanded:

div.RadTreeView .rtPlus {

 

    background-image: url("expandImage") ;

}

div.RadTreeView .rtMinus {
     background-image: url("collapseImage");
}


All the best,
