Hi,
I'm looking for an example of using RadDataForm to Update and/or Insert data in a SQL Server table in a WPF MVVM Light application.

I've binding DataForm with a LIST that contains a result of a sql query but I've not idea how to update or inser a value.

Thank's a lot!

I have two buttons one to show and other to close my RadDoking. By default, the RadDoking is deactivated(not show), when I press the show button, the RadDoking opens but on I prese my close button it does not work

My Xaml :


My ViewModel


My Converter 

I do not understand why it does not work, Thank you for your help :) 

Hi,

I would like to know how it's possible in the header of each column to have only the first day instead of having the beginning and the end of the week.

Thank's
Alain

Hi Telerik
I have been working on a project with you brillant TreelistView for over a year now - so glad I bought your product!

But heres my little problem - and it is also not working in your own example:
In your DragDrop-example for radTreeListView, it is not posible to drop an item on the last item.
It is posible to drop on all the other elements - except the last one.
Could you please help me with a workaround?

With kind regards from Kenneth

How can I tell whether Esc is from an Insert or Edit in a KeyboardCommandProvider?
Thanks in advance,
Steve

Per this post (http://www.telerik.com/community/forums/wpf/gridview/edit-mode-and-the-keyboardcommandprovider.aspx) it was recommended that I implement key handling for navigation by handling PreviewKeyDown. This was working fine up until the latest version of the GridView control, in my case, Q1 2011. If I press the down arrow while in a text box in edit mode, it should move down, select the next box and then go into edit mode. Now, the cursor does move down but the cell does not enter edit mode. This is the code that's been working for some time:

        private void HandleKeyDown(KeyEventArgs e)
        {
            if (e.Key == Key.Down)
            {
                RadGridViewCommands.MoveDown.Execute(null);
                RadGridViewCommands.SelectCurrentUnit.Execute(null);
                RadGridViewCommands.BeginEdit.Execute(null);
 
                e.Handled = true;
            }
        }

Hi,

we use the SchduleView to plan our staff. Works great and we are very happy with this control. Now we have this situation:

Two employees are planed for the same service oder. Now I we change the time for this work by moving the appointment from
one employee and we want, that the second appointment of the second employee will move too! Is this possible and how do
we solve this?

Thanks a lot
best regards

Hi,

I have a solution using RadDiagram in RadDocumentPane.
This Solution worked with RadControls_for_WPF_2013_3_1204_Dev.
After installing RadControls_for_WPF_2013_3_1306_DEV_hotfix the (see below) errors occured.
Installing RadControls_for_WPF_2013_3_1313_DEV_hotfix did not solve the problem.

My (Reduced) XAML:


The Errors:
System.Windows.Data Error: 4 : Cannot find source for binding with reference 'ElementName=grdHolder'. BindingExpression:Path=DataContext; DataItem=null; target element is 'Grid' (Name=''); target property is 'DataContext' (type 'Object')
System.Windows.Data Error: 4 : Cannot find source for binding with reference 'ElementName=dGram'. BindingExpression:(no path); DataItem=null; target element is 'XDiagramNavigationPane' (Name=''); target property is 'Diagram' (type 'RadDiagram')
System.Windows.Data Warning: 4 : Cannot find source for binding with reference 'ElementName=DropDownButtonElement'. BindingExpression:Path=IsChecked; DataItem=null; target element is 'DropDownMenu' (Name='DropDownMenuElement'); target property is 'IsOpen' (type 'Boolean')

The last Error is known for a long time (and also exists in my working solution - but has no negative effects so I simply ignored it)
See:
http://www.telerik.com/community/forums/wpf/docking/binding-error-using-raddocking-with-documenthost.aspx

But the first two (for grdHolder and dGram) occurred first after installing the hotfixes.
The result - no Diagram content.

A first fix was to change the xaml like this:


Removing the DataContext binding on the Grid brings back the diagrams functionality - but still the error:
System.Windows.Data Error: 4 : Cannot find source for binding with reference 'ElementName=dGram'. BindingExpression:(no path); DataItem=null; target element is 'XDiagramNavigationPane' (Name=''); target property is 'Diagram' (type 'RadDiagram')

is there - so I have an empty NavigationPane.

I have a RadOutlookBar with several textboxes within the RadOutlookBarItem.  When I run the code I am unable to tab through the text boxes.  Is there anything special I have to do to be able to tab through the controls?
