I just did a quick test of the Tree sample, and was surprised that it didn't work. I would think this should be possible, but I don't have time at the moment to look into it.

Last post by Mbk Hk - February 17, 2025, 02:43:41 PM

after several attempts to manually sort the elements of a Tree (Drag N Drop), using "DragOverFromControl" events, I was unable to achieve this.
Now I'm wondering if it's possible to change the position of an item (within the same parent) programmatically?
So if an item "Test2" is the 4th child of "TestParent", change its position to became 7th !

Thanks !

Image lists are designed and optimized for creation at design time, for embedding as a resource inside the .odcl file.

Hello.
when using "dcl-ImageList-SetAt" to add multiple images to the control imagelist it takes too long (around 6~7 seconds for 100 images).
while creating an imagelist through a .Net C# code for the same number of images takes no time.
how to work around this problem.and is there a way to pass the control imagelist to a .Net C# code to process adding/removing images from the imagelist using .Net C# code?
i tried to pass the Ename Handels to an C# code but it failed to read the passed Ename.

thank you for Helping
