Hello,
I want to use the TileView in the same way you used it in the example with the cars but when I add more items, I want to have them with a scroller where they are minimized on the right (like in the example with the flags). Could you please point me to how I can achieve it.

If it's simpler, tell me how can I modify the flags example so it will also be possible to be in a state that all the tileview items are in the same size (Normal state).

Thank you

LostFocus event fires everytime

Hi,
I have a datagrid which has template columns in it.
When i click a cell for editing, the grid's lostfocus is fired.
What i want to do is when the user edit a value in a cell and click outside the datagrid ie: on other control or the window its containing, i need to do something.
I tried to check !Datagrid.IsFocused and tried to do something when the grid doesn't have any focus. But that check always fails when i click outside the datagrid.

Any idea how to solve this?

Thanks

use GridViewSelectColumn as only method of selection?

Hi -
I want to use the GridViewSelectColumn as the ONLY method of row selection. Desired behavior: if a user clicks on a row, nothing will happen. But if they click on the checkbox in the GridViewSelectColumn, the row will be selected. In addition, the header checkbox in the GridViewSelectColumn must continue to select/de-select all rows. How can I best achive this?

I have tried setting the CanUserSelect=false on a grid containing a GridViewSelectColumn. This works fine for individual rows (only allowing row selection via the GridViewSelectColumn), however, if I click the GridViewSelectColumn Header checkbox, nothing happens (no rows are selected/de-selected).

I have also gone about handling the DataGridCell_PreviewMouseLeftButtonDown and DataGrid_PreviewMouseLeftButtonDown events, which allows the GridViewSelectColumn Header checkbox to work correctly, but it's definitely a hack, and not something I can easily implement across the many RadGridViews in my application.

Any help is appreciated.

Unable to dock pane after a LoadLayout

Hi,

I am attempting to use SaveLayout and when our app is re-run I use LoadLayout. Unfortunately, if the user floats a pane and then exits the app (saving the layout), and later re-runs the app and I load the layout, the floating pane is no longer able to be docked.

Looking in the XML that's written I see the RadSplitContainer is written with InitialPosition="FloatingOnly" which seems suspicious. I tried manually updating the XML file to set InitialPosition="FloatingDockable" but the pane is still not dockable.

If it matters, I do have SerializationTag set for all my panes, splitters and panegroups and do override the ElementLoaded event to plug in my own children of each pane (that part is working great).

Does anyone know what I can change to make the reconstituted Pane dockable again?

Thanks,
John

GridView cell selection

Hello guys

I'm evaluating RadControls for WPF and OA ORM for my next project. I'm just playing with it for just one day, but I'm already impressed with your work guys. Though, as a beginner, I can't figure out how to select a cell when new row is added to gridview. In other words, I want to select first editable cell and put it in edit mode when new row is added from InsertRow button. How is this accomplished?

EDITED
_____________________________

I will ask this one too here.
When cell validation fails, it would be nice to show the error message, without the need to move the cursor to the cell's red point. Is it also possible?

EDITED 2 :)
____________________________

is it possible to tell gridview not to change selection until all cells of the grid is validated? now it's possible to persist rows despite validation failure, which breaks business rule.

thanks

Multiple RadControls entries in the Toolbox

We have identified several occurrences of multiple/duplicated ToolBox items existing in the Visual Studio Toolbox. Unfortunately these seem to stem from a glitch in Visual Studio, which was still not reproduced reliably so that we can fix it, or ask Microsoft for a fix.

Below are the different kinds of occurrences and their possible fixes:

    * Duplicate Toolbox items, remaining two entries per control:
          o this could be a result of having parallel RadControls installations, which is the correct behavior (Visual Studio 2008 only)
          o this could be the result of an improper deregistration of an older RadControls distribution, followed by the registration of the newer one. Usually either of the two approaches below helps fixing the problem:
                + Close Visual Studio instances, start Windows Explorer, navigate to %localappdata%\Microsoft\VisualStudio\10.0 and delete the *.tbd files
                + Right-click the Toolbox inside Visual Studio and click Reset
    * Multiple entries per control, number increasing with each start of the IDE: this is the worst scenario we have come across. All the registry entries and files on the customer machine seemed fine in this case. The only fix we were able to apply was a complete uninstall of RadControls and Visual Studio 2010, followed by a clean install of the IDE and the RadControls.
