C datagridview cellvalidating example

To perform any custom validation on the cell or row being edited, you can use the Cell Validating and Row Validation events, respectively.

What's the best place to implement validation logic code and conditional formatting code for a Data Grid View?

In a lot of books and articles that I've read on this control, it seems to suggest that the appropriate event to handle for this is the Cell Validating one. However, this event triggers a bit too often for my tastes and I'm not sure it is required.

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.

This property returns the new value entered in the cell.

If it is less than five characters, you set the Error Text property of that cell to some error message.

Notice how the Column Index and Row Index properties of Data Grid View Cell Validating Event Args parameter are used.

At run time, if the validation fails, the Data Grid View displays a red exclamation icon in that cell (see below).

Since i have a column name as "Item Name" which is supposed to be entered as text there is an issue in the code.

It generates an error message when i type in the name of the item.

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.
