Hello,

I have a treeview where the root nodes are loaded at first and evertime a node is clicked the children nodes are loaded. for each node the Image is also loaded dynamically. For some nodes we Show just one Image and for some nodes we load and Image which has to be overlapped with another Image with relative Position set to bottom right. Can we achieve this ? if i use treeviewmodel imageURL i can only provide one Image. Can i overlap 2 Images and Show them in treeview

Thanks

Anamika

Hello,

The treeview supports a single image URL but it is possible to show an additional image by using one of the following approaches:
  • Use the SpriteCssClasses property to set a class with the with the needed background image.
  • Disable the encoding with the Encoded property and add the image to the item text.
  • Use a template for the items.

Hello Anamika,

You can overlap the second image with CSS e.g.
item.Text = "<img class='overlap' src='" +  model.AdditionalImageUrl +"' />" + model.Text;
.overlap {
    position:relative;
    left: -10px;
    top: 5px;
}
