Questions on UI for WinForms Forum

I'm having a issue with the hot tracking of input controls hosted on a WindowsFormsHost in an WPF application.

The situation is a host that has half a dozen RadTextBoxes on it, stacked vertically. We have our own custom theme which hot tracks the mouse movement by changing the border of the text boxes - much in the same way that the Windows 7 theme does, going from grey to blue when the mouse moves over the control.

If I now move my mouse up and down the form, going back and forth over the text boxes, the border colour changes don't always change correctly. It basically seems a little random. There are no issues with any of this functionality if I'm using the controls in a WinForms applications.

I'm not sure whether this is a WindowsFormsHost problem not catching the hover events properly, or a problem with hosted telerik controls, but any help would be appreciated.

Thanks

Tooltip for textbox portion of radspineditor?

When I subscribe to the tooltip needed event of radspineditor, I find that the tool-tip only appears when mouse hovers over the arrow buttons of radspineditor element. How can I make sure that the same tool-tip also displays when mouse is over the text box portion of radspineditor?

I am using 2008 Q1 SP1 version.

Thanks
Sunil

Building items in PropertyGrid at design-time

Is there a way to build the set of Categories and Items shown in a PropertyGrid at design-time? I realize that the focus of the PropertyGrid control is to dynamically bind to an object to allow access to changing the object's property values, so this may be outside of the original purpose of the PropertyGrid control. I really like the look and feel of the PropertyGrid with being able to organize fields by categories and provide custom editors for changing the values, and so I'm looking to be able to setup the PropertyGrid at design-time with my own pre-defined set of Categories, and then add Items under each Category, and databind each Item's value to an object's property. Similar to how you build the columns of a DataGridView at design-time, and set the "DataPropertyName" that you want that column to be bound to.

It doesn't appear that you can do this directly with the current RadPropertyGrid control, but is there way to get this kind of functionality using RadPropertyGrid, or another Telerik control that would offer this?

RadTreeView Filter problem

Hello. I have two problems with filtering in RadTreeView control.
1. I add nodes to tree when filtering is enabled.

Code:

radTreeView1.Filter = "new";

radTreeView1.Nodes.Add( "new Node" );

for ( int i = 0; i < 1000; i++ )

{

radTreeView1.Nodes.Add( new RadTreeNode( "test" ) );

}

You can see that after this actions scroll does not work correctly (see screenshot 1).

2. Some node is added to tree when filter was enabled.

radTreeView1.Filter = "new";

var node = new RadTreeNode( "test" );

radTreeView1.Nodes.Add( node );

After some actions I must to check if node was added. When node was not added I add it again.

if ( radTreeView1.Nodes.Contains( node ) == false )

{

radTreeView1.Nodes.Add( new RadTreeNode( "test" ) );

}

I don't know how to check is node is present in tree. When node is filtered it is absent in Nodes.
How can I check that node is present in tree?

Automatically add missing parent nodes

I was expecting that calling AddNodeByPath would automatically create the necessary parent nodes similar to how Directory.Create() works.

treeView.AddNodeByPath("General\\Billing\\February\\Report.txt")

treeView.AddNodeByPath("General\\Billing\\March\\Report.txt")

treeView.AddNodeByPath("General\\Billing\\April\\Report.txt")

However, it just seems to add them all to the closest node it could find (if there are no nodes, then a bunch of "Report.txt" will be in the root node).

I have come up with the following to solve this issue, but I'm wondering if there's an easier way?

private RadTreeNodeCollection AddNode(string path)

{

if (path == String.Empty)

return treeView.Nodes;

string node = Path.GetFileName(path);

RadTreeNodeCollection parent = AddNode(Path.GetDirectoryName(path));

if (parent.Contains(node))

return parent[node].Nodes;

else

return parent.Add(node).Nodes;

}

Is this a bug, or is it documented somewhere that AddNodeByPath() doesn't create the necessary parent nodes?
