Get current cell column index in DataGridView CurrentCellChanged Event

问题

I have the CurrentCellChanged event handler of a DataGridView and i want to be able to access the current selected cells column index from the event handler.

I used to have the code in the CellClick handler which has DataGridViewCellEventArgs as a parameter so i was able to get the column index from the event args parameter but the CurrentCellChanged event has EventArgs as parameters which i believe is supposed to imply that theres no data for this event.

Is there a way to access the new currently selected cells column index?

回答1:

Use DataGridView.CurrentCell property ..

http://msdn.microsoft.com/en-us/library/system.windows.forms.datagridview.currentcell.aspx

int columnIndex = dataGridView.CurrentCell.ColumnIndex;
int rowIndex = dataGridView.CurrentCell.RowIndex;

Use the DataGridView's CurrentCell property.

void dataGridView1_CurrentCellChanged(object sender, EventArgs e)
{
    MessageBox.Show(dataGridView1.CurrentCell.ColumnIndex.ToString());
    MessageBox.Show(dataGridView1.CurrentCell.RowIndex.ToString());
}

If you wanna check it with header of the column then

dataGridView.CurrentCell.Column.Header

回答4:

It's worth noting, that if someone is using WPF (with the DataGrid, rather than DataGridView), they can simply do:

DataGrid currentGrid = sender as DataGrid;

and then

currentGrid.CurrentColumn.DisplayIndex

or

currentGrid.CurrentCell.Column.DisplayIndex
