I have implemented a "Property Editor" style control for our application that utilizes a RadGridView.  By utilizing standard and custom .NET attributes, we allow for custom editing of properties from any user-configurable object within our product.  The user is also able to display properties alphabetically or by category.  I implement editing by creating a custom column type that inherits from GridViewDataColumn and overrides the CreateCellEditElement method.

The RadGridView has really served us nicely in this respect.  Recently, a request was made to support "Password" class properties.  Implementing the editor was trivial using the PasswordBox control.  However, I'm running into issues when trying to mask the password's value when not in edit mode.

Currently, I have defined a style that sets the Foreground font color to "Transparent" if the editor type is "Password":


This style is then utilized by the custom column class (inherited from GridViewDataColumn):


This works well, but it's not was I would like to do.  By setting the foreground font color, it gives the impression to the user that their entry was not accepted by the program.  I would really like to mask the password with a character in the cell similar to what the PasswordBox control does.  When I attempt to set the ContentTemplate with a control (TextBlock or PasswordBox), I loose the ability to edit the cell's contents.  The row will go into edit mode, but the edit control is not displayed even though the CreateCellEditElement method is being executed.

What's the best way to implement such a method of data masking?

Hello everyone,

There has to be a way to do this.
Problems

1. What I am trying to do it bind a list<Objects> to a series to have multiple series on the chart show. But there will be an unknown amount of Series each time so I can't hard code everything series mapping. Is there a way to have one series mapping definition set and bind a collections of objects to it?

2. After I have the series mapping done I am looking to do some simple filtering through the chart legend. Would there be a way to do this with the none hard-coded series mappings?

Please help

Thank you

Hi,

I have a radgridview that is bound to an observablecollection containing 16 properties, one for each column of the radgridview.  I have an WCF service that I poll every second, updating the observablecollection and thus, updating the radgridview.  I'm doing this with a dispatchertimer that fires a backgroundworker.  This works quite smoothly, although larger result sets (more than 50 rows) cause the GUI to freeze and/or the radgridview to "blink" momentarily.  Those, I'm assuming are limitations of WPF's threading abilities.  Anyhow, the largest problem I have is that on radgridview's that scroll vertically, when a user scrolls down, the grid scrolls all the way back to the top whenever the collection changes.  

I'm using Row and Column virtualization, if that makes any difference.  

Is there a way to make the grid not scroll to the top when the collection changes??

Hi

I want expand some row at run time in gridview and treeview. Please help me.

Hi,

I have a self referencing grid view in a output.xaml and having an event in the ViewModel.

Calling this event while adding new items in the other screen (to add the Grid view Headers).

Add couple of Headers and click the Output tab to view the values in the Grid View. Now its showing the grid with parent child relationship and the headers.

Now if I go and add a new header then the event will be called in the ViewModel of the output and binding the grid to show the new headers and the relevant values for the column. Here I am facing problem that while re-binding it takes time and binding the grid without the self referencing hierarchy. it just binds all the rows in the datatable property as the parent node.

Anybody knows where i have made the mistake.

Thanks,
Ramasamy
