DataGridView.IsCurrentRowDirty remains true after I commit changes to the database. I want to set it to false so it doesn't trigger RowValidating when it loses focus.
I have a DataGridView bound to a BindingList<T>. I handle the CellEndEdit event and save changes to the database. After saving those changes I would like DataGridView.IsCurrentRowDirty to be set to true, since all cells in the row are up-to-date; however, it's set to false.
This causes problems for me because when the row does lose focus it will trigger RowValidating, which I handle and validate all three cells in. So even though all the cells are valid and none are dirty it will still validate them all. That's a waste.
Here's an example of what I have:
void dataGridView_CellValidating(object sender, DataGridViewCellValidatingEventArgs e)
{
// Ignore cell if it's not dirty
if (dataGridView.isCurrentCellDirty)
return;
// Validate current cell.
}
void dataGridView_RowValidating(object sender, DataGridViewCellCancelEventArgs e)
{
// Ignore Row if it's not dirty
if (!dataGridView.IsCurrentRowDirty)
return;
// Validate all cells in the current row.
}
void dataGridView_CellEndEdit(object sender, DataGridViewCellEventArgs e)
{
// Validate all cells in the current row and return if any are invalid.
// If they are valid, save changes to the database
// This is when I would expect dataGridView.IsCurrentRowDirty to be false.
// When this row loses focus it will trigger RowValidating and validate all
// cells in this row, which we already did above.
}
I've read posts that said I could call the form's Validate() method, but that will cause RowValidating to fire, which is what I'm trying to avoid.
Any idea how I can set DataGridView.IsCurrentRowDirty to true? Or maybe a way to prevent RowValidating from unnecessarily validating all the cells?
