Validating datagrid values
Note that only the Cell Validating event can keep the editor active,when the validation fails and it does not allow the user to exit the cell until a valid value is filled.
However, pressing the Esc key in this situation will revert the initial value of the cell and it will close the editor. The Row Validating event has a slightly different behavior.
Canceling this event prevents the user from exiting the cell until a valid value is entered or the edit process is canceled (via Esc key).
The C# code snippet will enable the data cell validation in a textbox column for entering only none empty strings, which will disable the data validation and display the error indicator at the row header.The library provides a special extension to validate data in dhtmlx Grid on the client side (for server-side validation use the dhtmlx Connector library).Validation can be enabled for a whole column or for a specific cell. Empty Exit Sub End If Next End If End Sub Private Sub Data Grid View1_Cell End Edit(By Val sender As System. Show("Please enter numeric value.") Data Grid View1.
I mean, a certain column on my datagridview should accept integers only, otherwise, it will return a messagebox.
