I'm Developing a Windows Forms application with a datagridview bound to a datasource. In the process of validating some cell values the RowValidating Event does not fire when navagation moves off the row. Works fine moving to Next Row. However, if i change a cell value, Tab back to the left to another cell on the same row, then use the mouse to click on a Previous row above the changed row..... the RowValidating Event does not occur.
A B C D
1 x x x x
2 x x x x
3 x x x x
If I change the value in C2, then backtab (or mouse click) back to B2, Then mouse click on any cell in row 1, the RowValidation Event does not fire and thus the changed value in C2 does not get evaluated. I am manually handling the Datasource Update which is dependant on the validations. Please advise ...
