Dim Exporter As New Export.ExportToExcelML(activegrid)

Try

Exporter.RunExport(file)

Catch ex As Exception

MsgBox(ex.Message)

End Try

End Sub

Any idea how this should be written now?

thanks!

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

Exception thrown while filtering with a single quote

Hi,

When filtering is on, an exception is thrown when you press the single quote key (or apostrophe). I guess it's an expression injection problem or something like that.

Any solution ?

Thanks

Manually Re-Sort grid

Hi All,

I have a Grid bound to a Dictionary<> in C# (Actually bound to Dictionary.Values). I am doing this because I am editing the values of the grid pretty often and have a large data set, so using the dictionary allows me to find the exact element I am trying to change without looping through the entire collection.

This is working pretty well. I realize that a Dictionary doesn't provide notification when the collection is changed, so to show changes in the Grid I call the following 2 lines of code when I change any Dictionary element:

grid.TableElement.Update(GridUINotifyAction.DataChanged);

grid.TableElement.Update(GridUINotifyAction.StateChanged);

This shows all updates! Horray! However, it does not resort the grid correctly. So, if one of the fields that is being sorted changes, the rows do not move accordingly. I was hoping that I could determine when I might need to resort and call a "Resort()" type method, but it seems like I can't.

How can I get the Grid to resort in this scenario?

Thanks All!
