Validating datagridview - ghirl potup pakeshtan

hi there, this question have posted before also, but i ahave some more questions as well.when i try to validate the datagridview cell which evet should i use in the datagrid view.

When a user enters data in a cell under any column, I want to make sure they fill in the rest of the cells for that row. i and using the dgv Actions_Cell Validating event,but the thing is i want to validate the cell after the cell value has been selected.the code i have written does the validation when i click on another cell in the datagrid view.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.To perform any custom validation on the cell or row being edited, you can use the Cell Validating and Row Validation events, respectively.

If you want to validate the data cell by cell, the former event is useful where you want to validate the data for the entire row at once then the later event is handy.

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.

Question: How do I access what the user has typed in these circumstances?

I'm thinking that I should maybe End Edit before validating but I thought Cell Validating was an inherently "while-editing" event.

We are going through the following C# code to analyze the process of validating data in grid cell.
