Hi i am working vb.net08.
And present in my form one treecontrol and 3 buttons and one datagridview are there.
present my task is if i click any button first it should check the treeview control for each parent node if any parent node is expanded?? or Collapsed???

How can i write in a button click event for check each parent node is it expand or collapse???

Thanks

TreeView.SelectedNode tells you which one is selected. The TreeNode object (which comes back from the previous link) has a property called .IsExpanded which gives you the info you need. If you want to walk up and down the tree (ie parents, children) there are also properties for that on the TreeNode object.
