Tag is Nothing/null in NodeCheckChanged event

I am using the Tag property to store a DataRow for each node. It seems to work fine except for when I try to retrieve it in the NodeCheckChanged event where it is returned as nothing/null. If I iterate through the nodes and inspect the tag property, it is set properly. Has this been reported by anyone? I have a work around to just create a mirrored object to store my information in related by the absolute index of each node, but I would rather not do it that way.

TIA

Display Value instead of Code in Column

This question must be one of the top FAQ. But I cannot find a concise, clear answer. Let me try for a concise, clear question.

Given a "Lookup" table:

Code Direction
1 South
2 East
3 North
4 West

And a "Main" table:

Name Vehicle Code
Bert Truck1 1
Mac Truck2 4

How do I make the RadGrid display as follows? My RadGrid is readonly so no pulldowns are necessary on the third column.

Bert Truck1 South
Mac Truck2 West

I'm using OpenAccess ORM so my tables are in POCOs Lookup and Main.

Does the third column have to be a ComboBox column? Or do I use CellFormatting event? If I use a combobox column how do I set the three parameters (Main.Code, Lookup.Code and Lookup.Direction)?

Regards,
Guy

Sort in saved layout does not work

If a sort is saved as part of a layout it is not honored when the layout is loaded. The column header has the sort indicator (black triangle indicating ascending/descending), but the data appears in the order of the underlying data source, not the order specified in the layout.

If I click on the column header the data is sorted, but the sort added as part of the layout definition is ignored. It almost seems as though there is some sort of "apply" method that needs to be called.

I believe that this worked in 2010Q1, but is broken in 2011Q1.

CommandBarTextBox LostFocus Not Firing

I am having an issue and am on the very latest version of the controls where CommandBarTextBox elements placed in CommandBars do not fire the LostFocus events.

The following used to work, but since the last upgrade does not fire.

cbTextBox.TextBoxElement.TextBoxItem.LostFocus += new EventHandler(TextBoxItem_LostFocus);

I have also tried the code below, but again nothing happens.

cbTextBox.LostFocus +=new EventHandler(TextBoxItem_LostFocus);

I could use the TextChanged event, but for filtering large datasets I do not want to filter for every keystroke, only when focus is changed.

These are being hooked in the constructor so the events should be firing.

Any ideas?

Dropdownlist won't close when tabbing

Hi,

when I'm writing in the dropdownlist the dropdown is automatically dropping down. That's great. But when I try to leave the dropdownlist by tabbing whilst the dropdown still is dropped down, the dropdown won't close...

Am I missing something?

Best regards
Anders
