Problem with Controls on RadDocument

Hello

We have strange behavior on Twinhead Durabook T7M hardware (http://goldrushtechnology.com.au/Products/tabid/57/ProdID/2825/Default.aspx) OS: Microsoft Windows 7 32 bit.

When we try to activate the edit controls (f.e. RadComboBox) via the touch pen, they do not become active. Controls are provided by InlineUIContainer on the object RadDocument.

The result is that data can not be replaced via the touch pen. Edit controls have focus only for a fraction of a second, and then focus is lost.

When working with mouse there was no such problem. Installing other drivers for the touch pen did not help.

Problem occurs only for objects placed on the object RadDocument.

Version of Telerik software is 2013 Q2.

Best regards

Daniel Gontarek

Best Practices: Removing Columns from Grid

I have been using Persistence Framework to save the state of RadGridViews. The RadGridViews have a column chooser which enables the user to change the visible columns (IsVisible=true/false). The WPF program saves the state of grids on exit, and loads them when the program starts. This works very well.

However, recently, as part of an update to the software, I had to remove a column definition from the XAML and the Data Model. I noticed that when the program was loaded again, the column still appears (because I had chosen it in my grid) but the values are all blank.

My question is:
Are there any best practices for using the Persistence Framework with new releases of my software? For example, a way to force an update/automatically remove the persisted data for a particular grid that changes?

}

In my View I want to bind my datagrid to a the list of MyObject and have a display looks like :
Name                      | Option1 | Option2 | Option3 | ...
Object1Name          | true       |false        |true

How to pass value from datepicker when editing certain entry in a gridview?

How to pass value from datepicker when editing a existing entry in a gridview. For instance I have a column name ExpirationMonth with a cell data of AUG, and I want that to pass in a DatePicker Input, instead of seeing the watermark "Enter date". See the first Image.

The first image when editing a certain entry in a gridview, Aug does not show up in the ExpirationMonth, 2014 does not show up in Expiration Year.

Also when I add an entry still the same even it has a default value, set as

//for ExpirationMonth

DateTime.Now.ToString("MMM");

//for Expiration Year

DateTime.Now.ToString("yyyy");

But when I select a month for ExpirationMonth, month I selected appears in the DatePicker input. See the second Image.

What I did to show month and year in the Datepicker Input, here is the code snippet:

public CreditCardWindow()

{

InitializeComponent();

CultureInfo cultureInfo = new CultureInfo("en-US");

DateTimeFormatInfo dateTimeFormatInfo = new DateTimeFormatInfo();

dateTimeFormatInfo.ShortDatePattern = "MMMM";

cultureInfo.DateTimeFormat = dateTimeFormatInfo;

dteExpirationMonth.Culture = cultureInfo;

string dteMonth = dteExpirationMonth.SelectedValue.ToString();

dteMonth.ToUpper();

CultureInfo cultureInfo2 = new CultureInfo("en-US");

DateTimeFormatInfo dateTimeFormatInfo2 = new DateTimeFormatInfo();

dateTimeFormatInfo2.ShortDatePattern = "yyyy";

cultureInfo2.DateTimeFormat = dateTimeFormatInfo2;

dteExpirationYear.Culture = cultureInfo2;

}
