Can't drag and drop Win Tree control to a Win form
posted

hi all,

 I'm getting this strange problem. When I drag and drop a Win Tree control to a win form, the win tree control won't stay on the win form, instead it automatically goes to the component area below the form. I use V.S. 2008. All the other Infragistics controls work just fine.    And I noticed when I opened the sample WinTree Appearances project in my visual studio 2008, I was able to drag and drop a Win Tree control to a form in that sample project.       But if I create my own new windows project and add a new form, I can't drag and drop the win tree control onto the form.      Is there a form setting somewhere that causes this problem?

 thanks lot in advance..

 Tony..

    Hi Tony,

    If the tree control shows up in the system tray, it indicates that Visual Studio is unable to find the Tree designer assembly. 

    This can occur for a number of reasons. 

    Since the sample is working okay and a new project is not, my guess is that your toolbox is out of synch somehow and is referencing the wrong version of the assembly. Try running the Infragistics Toolbox Utility. NetAdvantage installs a shortcut to it on your start menu. This will remove the NetAdvantage toolbox tab and re-add it and that should fix the issue.
