Hi,

I created a user control that inherits System.Windows.Forms.TreeView so I could use the StateImageList to implementa tri-state checkbox treeview. For some of my nodes I don't have checkboxes, and I found setting node.StateImageIndex = -1 makes the node not display any space for the state image. So that works great.

However, I also want to display images on some nodes and not others. I expected to do the same thing: set node.ImageIndex = -1 for the nodes that I don't want to have an image. But when I do that, the nodes actually show the first image in the ImageList, as if I set the ImageIndex = 0.

So,is there any wayI canshow an image onsome nodes, and not on others?

Thanks,

David

Hi

Would mind paste some code here so I can know you problem clearly!

Sure - here's the idea:

MyTree.ImageList = MyImageList

node1 = new TreeNode("Has Image")

MyTree.Nodes.Add(node1)

node1.ImageListIndex = 0

node2 = new TreeNode("No Image")

MyTree.Nodes.Add(node2)

node2.ImageListIndex = -1

Unfortunately, node2 still displays the first image in the imagelist, as if I set it's ImageListIndex = 0.

What I want is no image to be displayed for node2.

Any thoughts?

Thanks,

David

Hi David,

Can you tell me, how to prepare a image List...(in WPF)

I did this::

List<Image> myimgList = new List<Image>;

Image img = new Image();

myimg List.Add(img);


Now how to Give The image to---> ' img '....???

I tried lik this-------- Image img = new Image("~Images/folder.png");(I have images in my project with folder name ' Images ')

But i got anerror---"--Error1'System.Windows.Controls.Image' does not contain a constructor that takes '1' arguments"---

and also tell me how to bind that Image List to TreeView

I prepared a List of menuitems for my treeview and it worked. When i am trying to do it in the same way for images its not working..

Please suggest me the Correct way to do this..

Thank you foryour support.
