Net datagridview cellvalidating
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??
How can I disable the cell validating event for the rows that was added before???

Although you used Data Set as the source of your data, you also could have used generic collections if required.
You can download the code that accompanies the article here.
The Data Grid View control of Windows Forms is a versatile control that can help you create professional-looking data entry forms.
It not only supports data binding but also provides frequently needed column types, such as combo box and button.
The Data Grid View event model is really extensive and one can take control of validation and entry by using many of these events.
Since you have not added your new row yet it should validate OK." yeah i think it is because of the line you have said above how can i avoid this situation???
thanxxxxxxxxxxx If you have attached an event handler to the Cell Validating event then it will always fire when focus leaves the cell.
Or if not, then it is because the user has entered an invalid value in the current cell.
