Raise cellvalidating event datagridview
In this situation the editor is not kept active when the validation fails and pressing the Esc key does not revert the changes as the editor is already closed.
What's the best place to implement validation logic code and conditional formatting code for a Data Grid View?
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.
How can I disable the cell validating event for the rows that was added before???
thankxxxxxx There are two ways to manage unwanted execution of event handlers.
1) Add a conditional statement in the event handler code to only execute when required.
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??
2) Detach the event hander before the unwanted event triggers and re-attach after. so when i click the add button the cell validating event triggers i have posted the cell validating event do you know how to solve this thanxxx code!!!
Now, since so many books use the Cell Validating event, I wonder if there is not any gotcha (in display for example) with using the Cell Value Changed?This scenario can be achieved by using the Row Validating event, which is fired when the user tries to change the current row (changing to another row or when the control loses focus).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.The Data Bound Item will be updated only if the cell is validated.However, the user may prefer to validate all the data cells in a row at once.
