Although the validation works perfectly, I want to highlight the row which generates an error and also display a tooltip. Make your Item object expose a “Is Valid” property then use a custom type converter to convert it into the background colour.Likewise for the tooltip, but that may need an Error Type property that is a enum. Every column contains textbox, except 2nd and 9th: there's a combobox in 2nd and image for drag'n'rop in the 9th.I need to validate my Grid View in the way that if any column in row is empty, I can't click save button.The key is the Format, which is set to one of the four enumerated Export Format values.public class Employee In Main cs, in the Loaded event handler, you’ll set the Items Source property for the grid to the result of calling Get Employees as shown in Example 6.public Main Page() Run the application to ensure that the Grid View properly displays the 15 records.There are certainly times when you do not want to send all of the possible records matching your search criteria to the client machine.
If the focus is moved to a cell in another row, then both Row Validating and Row Validated are fired, containing the whole row data, including the new and the old values of the edited cells.
