Want different node name from path generated

Hi,

I have a RadTreeView with a list of nodes, each of which should have a count after them.

Root (10)
-- Cars (20)
---- Ford (12)
---- Chrysler (2)
---- GM (30)

I realize I can use the tag to store a "value" for the node independent of the display format - I'm already doing that. However, when I export the data in the table, I make use of the convenient "Path" property to flatten out the hierarchy. Is there a way to generate the Path from the Tag property rather than from the Text property?

How would you go about exporting this to a list that looks like this?:

Root
Root/Cars
Root/Cars/Ford
Root/Cars/Chrysler
Root/Cars/GM

I'd rather not write the code to walk the tree and construct the paths myself - but it's the most practical solution I can think of.

RadGridView loses format when it is updated.

Hi, in my program I have a RadGridView. Some of the cells are formatted with different backgroundcolor or they are disabled. The first time I bind the grid with data read from a table of a database it shows correct but If I update the grid it loses the format (All the cells are white and enabled) .

The cells are formatted according to this approach http://www.telerik.com/community/forums/winforms/gridview/createcell-event-cellelement-is-always-null.aspx (First it sets a tag for each cell in DataBindingComplete and subsequently depending on this value it sets backcolor and enabled properties for the cell.)

Here is the code (Cheers to Emanuel Varga for it):

void radGridView1_CellFormatting(object sender, CellFormattingEventArgs e)

{

if (e.CellElement.RowInfo.Cells[0].Tag != null && e.CellElement.RowInfo.Cells[0].Tag.Equals(true))

{

e.CellElement.BackColor = Color.Red;

e.CellElement.DrawFill = true;

}

else

{

e.CellElement.ResetValue(LightVisualElement.BackColorProperty, ValueResetFlags.Local);

e.CellElement.ResetValue(LightVisualElement.DrawFillProperty, ValueResetFlags.Local);

}

void radGridView1_DataBindingComplete(object sender, GridViewBindingCompleteEventArgs e)

{

foreach (var row in radGridView1.Rows)

{

if (row.Index % 2 == 0)

{

row.Cells[0].Tag = true;

}

Thanks for the answers.

people picker / contact selector

In a current project we need a people picker (validator - against AD preferably), like the one eg. Sharepoint but can't seem to find one anywhere. Does Telerik provide something like it or does anyone else know of such control/dialog?

Is there anyway I can disable theming?

As I've reported before, the initial load time of my MDI Application is unacceptable. I searched around and found out that most of the initialization occurs in relation to themes. Is there a way I can disable themes for the entire application?

Thanks
