If you don’t specify a source explicitly by setting the Source property of the binding, it will inherit the Data Context from its parent element to use as its source.In a MVVM WPF application, the view model acts as the window’s Data Context: This means that that all controls inside the window will inherit its Data Context unless some parent element of a control overrides this by setting its own Data Context property.The following events are associated with Row Validation in the Data Grid control: When the Is Valid property is set to ‘false’, the editor of the current cell does not shift to focus.When you navigate away from the cell (outside the current row) that is in edit mode, the navigation is handled within the current row alone.You can enable the Validation mode in two different ways using Grid Validation Mode to In View or In Edit mode.
Provided that the view model has a property called “Name”, you bind it to a Text Box’s Text property in XAML the following way: Besides the path that specifies the name of the property to bind to, the binding must also have a source object.
You can use two different modes in Validation like ‘In View’ or ‘In Edit’. Output Sf Data Grid offers Validation through events when a cell moves into Edit mode and its focus is lost.
Validation is done through the following events: The event handler of the Current Cell Validating Event receives two arguments namely sender that handles Sf Data Grid and Current Cell Validating Event Args as objects.
This event is raised when the row is validated with the updated source, and the Row Validating event’s Is Valid is set to ‘true’.
The event handler receives two arguments namely sender that handles Sf Data Grid and Row Validated Event Args as objects.
