I wrote code in the cellvalidating event as follows. Data Grid View Cell Validating Eve nt Args) Handles Datagrid1. This helps identify when, and in what order, events are being handled without explicitly having to set breakpoints and wait for the code to catch each event.In the options group box, you can choose to include event handlers notifications or not.Changing the active status for a given person will not fire the event until some other object on the form is clicked and receives focus.Anytime a grid event is handled, a notification will pop-up and fade out.What if someone is able to make a selection without a click event?
You might want to handle this for a number of reasons: to enable a save button, to change the appearance of selected items, to display a pop-up window, or to check for consistency against other choices.
I need to check that only one of the two can be checked.
Its not permissible to have the two selected to true, but they can both be false.
When you click a Check Box in a Data Grid View Check Box Column, the check marker will update immediately, but Cell Value Changed event on the Data Grid View will not fire until the user happens to click elsewhere and the cell has lost focus. Well, the Data Grid View thinks it’s a little preemptive to go declaring that the cell value has changed while you are still selected on it.
This makes more sense when we think about a Text Box column.
