?//對于datagridview使用CellMouseDown事件

private void dataGridView_CellMouseDown(object sender, DataGridViewCellMouseEventArgs e)?
{?
if (e.Button == MouseButtons.Right)?
{?
?? if (e.RowIndex >= 0)?
?? {?
??? dataGridView.ClearSelection();?
??? dataGridView.Rows[e.RowIndex].Selected = true;?
??? dataGridView.CurrentCell = dataGridView.Rows[e.RowIndex].Cells[e.ColumnIndex];?
??? contextMenuStrip_ListViewItemRightClick.Show(MousePosition.X, MousePosition.Y);?
?? }?
}?

}

//對于treeview可以使用mousedown事件

方法一：
private void treeView1_MouseDown(object sender, MouseEventArgs e)?
{?
if (e.Button == MouseButtons.Right)?
{?
TreeNode node = this.treeView1.GetNodeAt(e.Location);?
if (node != null)?
{?
this.treeView1.SelectedNode = node;?
}?
}?
}

方法二：
void?jcsTreeView1_MouseDown(object?sender, MouseEventArgs e)
??????? {
?????????? System.Windows.Forms.TreeViewHitTestInfo hittestinfo?=?this.jcsTreeView1.HitTest(e.X ,e.Y);
???????????if?(hittestinfo.Node?!=?null)
?????????? {
?????????????? TreeViewHitTestLocations loc?=?hittestinfo.Location;
???????????????if(loc?==?TreeViewHitTestLocations.Label )
???????????????? MessageBox.Show(hittestinfo.Node.Text);
?????????? }
??????? }
