Hi,
I had a quick look in the PITS but didn't notice if this issue is in there.
There seems to be an issue with floating panes and using the Windows 7 Windows Key shortcuts.
Using WindowsKey + Down Arrow, will minimise the the floating window to somewhere and also and subsequent attempts to make any other panes floating fail. Dragging a window out of the tabbed documents also immediatly makes the about to be floating window disappear.
Using WindowsKey + Right (with two monitors) will send the floating window to the right of the secondary monitor, and will only allow it to be dragged within half of the screen width on that monitor, ie, it is given half the screen width and that is all. To move it back out, WindowsKey + Left can be used.
Thanks,
Adam

Hi,
Could any one guide me how can I edit the column footer style from Expression blend.. Actually want a single strip for agreegates, not different cells against each column. I can edit the group footer style but column footer style is note availble. For refernence, I am attaching a screen shot. THANKS

Hello :)
This is my scenario:
I have a gridview with a GridViewComboBoxColumn with the property isComboBoxEditable set to true and the ItemsSource property set to a List<T> (the data of this list is populated from a data base). The SelectedValueMemberPath set to a property of the T object and the DisplayMemberPath set to an another property of T. Everything works as expected.
I would like to know how can I do the following if possible:
The reason for the isComboBoxEditable is set to true is that I want the user to add new items to the GridViewComboBoxColumn, then I save this new item to the data base and then display the combobox with the new item. So how can I access the combobox and add the new item and then display the combobox list with the new item? I guess refreshing the combobox, refreshing the row, or refreshing the entire gridview could help because all the combobox in the rows created previously must have the new created item too.
I hope you can help me.
Best regards,
Jorge Alberto

Hi,
I upgraded to the Q2 release for WPF and I'm now getting intermittent NullReferenceExceptions coming from the following exception below.
This seems to be due to the fact that CoverRectangle is backed by a WeakReference.
What seems to be happening is CoverRectangle is being GCed during the drag operation. This may be due to the fact that in .NET 4 the GC is much more aggressive.
Thanks,
Kavan

this.grid.IsBusy = true;
Load_Invoices(); // Sets ItemsSource
this.grid.IsBusy = false;
// Blows up Here!
this.grid.SelectedItem = this.grid.Items[0];

Hello :)
I have use a GridViewToggleRowDetailsColumn in my gridview to enable the user to see the rowDetails of each row.
I would like to know how can I set a row as selected when the user click the button generated by the GridViewToggleRowDetailsColumn.
For example I have 5 rows and the current selected row is the first row, so when the user wants to see the details of the fifth row, he make visible the row detail by pressing the button generated by the GridViewToggleRowDetailsColumn and just before the user releases the mouse button I want to make this row the current selected one.
Is this possible? I hope you can help me.
Best Regards
Jorge

Hello,
I am having trouble setting the focus to a RadPane. This is true in both docked and undocked panes, However the undocked floaing pain is my main problem.
This is the code that I am using.
RadPane rp = lc.Pane;
rp.IsSelected = true;
rp.Focus();
Thank you,
