We have a DataGridViewCheckBox column bound to a boolean property in our class. The property setter has some logic which says that under certain conditions a True flag cannot be changed, ie, it stays checked forever. This is on a per record basis. So the entire column can't be readonly, only certain rows. Pseudo code: Public Property ...

This is the DropDownList, which has it's own datasource, which returns a List of Departments: <asp:DropDownList ID="DepartmentsList" DataSourceID="DepartmentsListDataSource" DataTextField="Name" SelectedValue='<%# Bind("Department") %>' runat="server" /...
I have a user control, A, which wraps a third-party date-picker control, DP. A tells DP's SelectedDate dependency property to two-way bind to A's SelectedDate dependency property, thus effectively exposing the wrapped date-picker's SelectedDate value. I then have a control X which contains an instance of user control A. This tells A's...

"The essence of a Presentation Model is of a fully self-contained class that represents all the data and behavior of the UI window, but without any of the controls used to render that UI on the screen. A...
So I have this datagridview that is linked to a Binding source that is binding to an underlying data table. The problem is I need to manual add rows to the datagridview. This cannot be done while it is bound, so I have to work with the databinding. If I add the rows to the underlying datatable, when the datatable is saved, the rows are...
OK, I've figured out how to get my Grid of UI elements to zoom, by using LayoutTransform and ScaleTransform. What I don't understand is how I can get my View to respond to CTRL+MouseWheelUp\Down to do it, and how to fit the code into the MVVM pattern. My first idea was to store the ZoomFactor as a property, and bind to a command to adj...

Does the JGoodies list binding support binding list contents to a list object in the model? I know I can add listeners to the list model and domain model and coordinate changes between the two fairly easily, but I wasn't sure if JGoodies would do that. I could only find list binding that dealt with list selection events. ...
I have a gridview databound to an objectdatasource. Everything worked great until I changed 2 columns from asp:BoundField to asp:TemplateField. These are the UPC column and the Part column. I wanted to show a link button for each of these fields that take the user to another page. Now asp.net expects these two fields to be parameters on ...

When I make a new call to the service, I want the exiting items to be flushed and bind the newly retrieved data to the same list. How can I achieve this? ...
