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?

[Solved] 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?

User interaction with the gridView

Hi,

I am using the hierarchical Gridview as some sort of navigation tree.
Typically, the Grid is positioned on the left pane, the right pane contains detail data an more.

When the user selects a row, from any level in the grid, extra data is loaded and displayed on the right pane.
Mostly, the detail pane contains a lot more data, than is displayed in the navigation grid. Depending on the network speed, this can take a bit of time.

My problem is that the grid, used as a data navigation aid, still accepts user interaction while detail data is being retrieved from the database.

Now I have to options:
1. fetch detail data in a separate thread, and abort when the user selects another row.
2. keep the grid (navigation aid) from processing user interaction while detail data is loading.

My question is,
can user interaction with the grid be placed on the same thread, so that it has to wait for the detail data being loaded?

Thanks.
