So the Cell Validating event cannot be fired when pressing the "Enter" key. The following code example shows how to use this event to validate the cell's value.
If you want the Cell Validating event to fire, assign the "Enter" key to the Selection Actions. To run this example, create a windows form, and add a Gc Multi Row control to the form.
There are two ways to manage unwanted execution of event handlers. Data Grid View Cell Validating Event Args' does not contain a constructor that takes '1' arguments" what is the solution for this???????
1) Add a conditional statement in the event handler code to only execute when required. Cell Validating -= new Data Grid View Cell Validating Event Args(dgv Sub Contractor_Cell Validating); it says that "Error 7 'System. hey what do ouy mena by the below private void data Grid View1_Cell Validating(object sender, Data Grid View Cell Validating Event Args e) if (adding Row) - is to call the button event for adding a new row is it every time the cell validating event triggers and a value is entered in the datagridview cell right??
The event handler receives an argument of type Cell Validating Event Args containing data related to this event.
The following Cell Validating Event Args properties provide information specific to this event.
However, if the failing validation is preventing the cancel button from doing its thing, set the @Daniel Schaffer: i'm not sure if I understand the "however"-part correctly.
How can i prevent the validation from taking place when the user hits the cancel button?
The validation triggers a messagebox which is always shown even if the user wants to cancel editing/adding an object because the validating happens before the button-click.
If the buttons parent has Causes Validation set to true, the validating event will still get called.
In one of my cases I had a cancel button on a panel on a form, so I had to set Causes Validation = false on the panel as well as the form.
