Overriding native input parsing

My company is using RadControls for WPF Q1 2010 SP2. I am extending the RadDatePicker control to add certain behaviors that are used by our FSP suite of programs. We are using Visual Studio 2008 and C#.

When an invalid date is typed into the input box of a RadDatePicker (for example, 13/35/2011), its native behavior is to clear the field. I need to override this behavior to keep (not clear) the invalid input and set an error message property in our extended control. Is this possible and if so, how do I do that? I am not very experienced at how to code event handlers so if you could provide the code for how to hook the event and the skeleton of the new event handler, I would appreciate it.

Would this technique work for the RadTimePicker as well? I need to do the same thing to it.

Thanks,
Mike

Funky formatting in Localization help

Hi,

Just wanted to mention that the formatting on the Localization help page is a little funky:

http://www.telerik.com/help/wpf/radtimebar-localization.html

This also spreads across to related product lines (for example, Silverlight).

Kind regards,
Dave.

Tabbing out of a RadRichTextBox

Hi,

I'm implementing keyboard navigation in an application. When I tab into a RadRichTextBox and press tab again to skip to the next control a tab character gets added to the RadRichTextBox instead. Now I understand that the tab command in the Rich Text Editor means something other than to skip to the next control but I was wondering if it would be possible to 1) disable this behaviour and skip to the next control or 2) is there another keyboard command that would "tab out" of the Rich Text Box and skip to the next control?

Thanks,

-- Joel

How to show busy indicator before closing window?

Hi,

I have an application that when the user close the window, I'd like to do some time consuming task (update database). At the same time, I want to show busy indicator. When the task is done, close the window as per normal. Here's the sample code

public partial class MainWindow

{

public MainWindow()

{

InitializeComponent();

Closing += MainWindowClosing;

}

void MainWindowClosing(object sender, CancelEventArgs e)

{

e.Cancel = true;

busyIndicator.IsBusy = true;

var worker = new BackgroundWorker();

worker.DoWork += (s, args) => Thread.Sleep(TimeSpan.FromSeconds(3));//just for testing

worker.RunWorkerCompleted += (s, args) =>

{

busyIndicator.IsBusy = false;

e.Cancel = false;

};

worker.RunWorkerAsync();

}

but it's not working. The "e.Cancel = false" doesn't close the window. Can anyone help? Where did I do wrong?

Thanks!

Live Data Chart

I am trying to create a chart very similar to the Live Data chart in the examples. When my timer runs the data is updated but not shown on the chart. However, if I break into the timer event and look at some values in the debugger and then eventually tell the app to start running again then I sometimes will see some of the data drawn on the chart but it still does not update in real time.

We are using the latest WPF controls.

PS: Apparently we can longer attach files?

A sample project can be found here: sample project

Unable to add Columns to RadGridView after being added as a FrameworkElementFactory

I have a RadGridView that is part of a datatemplate that I am creating at runtime via c#. All is good if I AutoGenerate the columns. If I try to create the GridViewDataColumns I have no way of adding them. Seems the Columns property is not exposed as a dependency property. Can you please look into this and suggest a work around or possible solution? In my example, RadGridView.Columns does not appear to be accessible.

FrameworkElementFactory radGridView = new FrameworkElementFactory(typeof(RadGridView));

radGridView.SetValue(RadGridView.ShowGroupPanelProperty,false);

radGridView.SetValue(RadGridView.ShowInsertRowProperty, false);

Telerik.Windows.Controls.GridViewColumnCollection colCollection = new Telerik.Windows.Controls.GridViewColumnCollection();

GridViewDataColumn dc = new GridViewDataColumn();

dc.Header = "test"

colCollection.Add(dc);

radGridView.SetValue(RadGridView.Columns,colCollection);
