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??
Unfortunately the code only allows integers to be entered in the datagridview.
Since i have a column name as "Item Name" which is supposed to be entered as text there is an issue in the code.
If there are cells that you dont want to validate (eg read only cells) then add a check at the start of the event handler that will cause it to exit if it is trying to validate those cells.
For instance, if column with index 2 is read only and you dont want to validate cells in that column you could use: If you have attached an event handler to the Cell Validating event then it will always fire when focus leaves the cell.
Cell Validating Dim header Text As String = _ data Grid View1.
"The validating event is firing because focus is being moved from the DGV to the button. Data Grid View Cell Event Args) _ Handles data Grid View1.

Storing sensitive information, such as a password, within the connection string can affect the security of your application.Hi there, I have a question regarding datagridview, I add data to the datagridview in an interface and all the validation for the datagridview cell is in the datagridview cell validating event for the datagridview.I display the data of the is datagridview in another interface and make the cells read-only. But the thing is when I click on a row that data was added previously and press the Add new row the cell validating event is triggered.
