Hello!
In my CellValuePresenter I defined a XamNumericEditor that is using an other XamNumericEditor as EditTemplate. The difference is that I want to bind the Value property to an other source.
Unfortunately I have to double click in the cell to start edit mode (so that the masked is displayed). If I click once the field takes the entered chars, but does not show it in the control.
How can I start edit mode by click only once in the field? Or even better might be, if edit mode starts when the field gets focus (if the user uses tab to go though the grid)!
Please check out the attached example!
Thanks, Florian
No ideas or comments? Does anyone have the same issue?

Started this topic a long time ago, but I am still interested in a solution!
Hi Florian,
I still do not fully understand what is the end result you are trying to achieve . E.g. why aren't you using the DoubleValue property only. If there is some manipulation over the DoubleValue that you want to do before you showing it to the user you can do it in the get method without affecting your private property, or if you it would be like a formatting of sorts you can do it in the XamNumericEditor’s ValueToDisplayTextConverter.
Please try and elaborate your descriptions so I get you overall goal. Thanks in advance. Looking forward to your reply.

Hi,
the reason why I cannot use DoubleValue only is the following. I want to display the property Value, which is a calculated value. But when the user starts editing he should work on DoubleValue, because when the user starts editing, he should see the value he is changing. And this is DoubleValue.
I added a slightly modified example.
Hope this makes things clearer. I tried to focus on my issue.
thanks, Florian
This is exactly what I had understood last time, so I have modified your sample in a way that I myself would go for if I need such functionality. I have used a simple custom ValueConverter class on the XamNumericEditor and have disposed of your CellValuePresenter template, thus preserving all its functionality along with the XamNumericEditor’s.
Please test it out and let me know if this is what you were looking for, or if you require any further clarification on the matter.
Good Morning,
thanks, this works if the calculation can be done wihtout knowing the ValueContainer. But only the ValueContainer knows how to calculate the value that shall be displayed. Please check out my second example in WpfApplication2.1.zip.
In the ValueConverter I have no access to the ValueContainer. How can I access the ValueContainer in the proposed solution?
regards, Florian
Hello Petar!
OK, I found a very easy solution I think. I defined a Style-Trigger that watches the IsInEditMode of the XamNumericEdit. If it is in edit mode I use a binding to the DoubleValue field of the ValueContainer, and if it is not in edit mode I bind to the Value property (which is the calculated one).
Advantages of this solution is that I can do my calculation in the ValueContainer (where I have all the values to calculate) . Addtionally I do not need to have a separeted ValueConverter.
Petar, maybe you can quickly check if this is a proper solution. I attached my solution.
Thanks to open my eyes and pointing me into the right direction. Regards, Florian
