RadGridView detect CellClick event button

问题

How can I detect which mouse button was pressed in event CellClick, or how can I detect which cell was pressed in event MouseClick.

回答1:

You can detect which cell was clicked by using Mouse Click event.

Then you have to cast sender to RadGridView, and then use CurrentCell property.

GridViewCellInfo dataCell = (sender as RadGridView).CurrentCell;

If you want to which mouse button was clicked use:

if (e.Button == MouseButtons.Right)
{
//your code here
}

I have written this answer thinking that you meant DataGridView; but this code might also be useful for RadGridView. What I usually do in these cases (with DataGridView) is relying on a global flag to coordinate two different events; just a few global flags should be OK. Sample code:

bool aCellWasSelected = false;
private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
{
    aCellWasSelected = true;
}

private void dataGridView1_MouseClick(object sender, MouseEventArgs e)
{
    DataGridViewCell selectedCell = null;
    if (aCellWasSelected) 
    {
       selectedCell = dataGridView1.SelectedCells[0];
       MouseButtons curButton = e.Button;
       //Do stuff with the given cell + button
    }

    aCellWasSelected = false;
}

NOTE: the proposed global-variable-based approach is NOT the ideal proceeding, but a practical solution pretty handy in quite a few DataGridView-related situations. If there is a direct solution, as in this case (as proposed in the other answer or, in DataGridView, the CellMouseClick event), you shouldn't ever use such an approach. I will let this answer as a reference anyway (for people looking for equivalent two-event-coordination situations, where no direct solution is present).
