MultiColumnTreeView

[Josh Collins]

I cannot get vertical scrolling to work with a multi-column tree view.

Attached is a project exhibiting the behavior.

Using VS.Net 2005 C#.

I have tried 5.1.1.9 and 5.1.1.41 and both exhibit the same issue.

I cannot change the VScroll property in the designer (switches back to false).
Setting it to true in the code or using tree.AutoScroll = ScrollBars.Vertical does not affect it.

I have seen this thread below, but didn't see any real resolution.

I need a solution to this ASAP.

Thanks,

Hi Josh,

The default behaviour of MultiColumnTreeview is that the Vscroll and the HScroll properties can only be set when the number of nodes populated at design time or at runtime are more than the controls view area. The Scrollbars will only appear when the number of nodes loaded are more than the TreeView height, provided we set the Vscroll to true after loading the nodes.

Kindly try it and let me know if this helps in resolving your issue.

How would this work if the control is docked to 'fill' and the height of the control is variable?

Are you suggesting that I set VScroll = true after all nodes are loaded and after each node expansion?

Why is this behavior so much different from the expected behavior of the TreeViewAdv

Hi Josh,

Here is the details for your questions,

How would this work if the control is docked to 'fill' and the height of the control is variable?

- The Scrollbars will appear when the number of nodes loaded are more than the TreeView height

Are you suggesting that I set VScroll = true after all nodes are loaded and after each node expansion?

- you need to set the VScroll = true after the nodes are loaded. Since the scroll cannot work on empty node collection.

Kindly let me know if you need any additional details,

Setting VScroll to true after the nodes are loaded does not fix my issue. After the nodes are expanded to the point where it should scroll, the vertical scroll bar does not appear.

Hi Josh,


The Scrollbars appears only when the number of nodes loaded are more than the TreeView height. So it is necessary to set vscroll = true after each node expansion. Here is a sample for your reference,

Kindly take a look at the sample and let me know if this helps in resolving the issue.
