我有一个datagridview,我显示关于产品的信息.我想绑定一个上下文菜单,当用户选择一个单元格,然后右键单击该单元格.我有另一个上下文菜单,并且绑定到datagridview的列.如果用户右键单击上下文菜单显示的列.
我已经尝试过这样但是不行.上下文菜单显示用户右键单击单元格,但是绑定到列标题的上下文菜单不起作用.
private void GridView1_CellMouseUp(object sender,DataGridViewCellMouseEventArgs e)
{
if (e.Button == MouseButtons.Right)
{
productContextMenu.Show(GridView1,e.Location);
}
}
提前多次.
编辑
Thnx为答案.我解决了这个问题：
private void GridView1_MouseUp(object sender,MouseEventArgs e)
{
DataGridView.HitTestInfo hitTestInfo;
if (e.Button == MouseButtons.Right)
{
hitTestInfo = GridView1.HitTest(e.X,e.Y);
if (hitTestInfo.Type == DataGridViewHitTestType.Cell)
{
productContextMenu.Show(GridView1,e.Location);
}
}
}
解决方法
尝试这个
private void dataGridView1_CellMouseDown(object sender,MouseEventArgs e)
{
if (e.Button == MouseButtons.Right)
{
contextMenu.Show(datagridview,e.Location);
}
}
要么
private void dataGridView_MouseUp(object sender,MouseEventArgs e)
{
// Load context menu on right mouse click
DataGridView.HitTestInfo hitTestInfo;
if (e.Button == MouseButtons.Right)
{
hitTestInfo = dataGridView.HitTest(e.X,e.Y);
// If column is first column
if (hitTestInfo.Type == DataGridViewHitTestType.Cell && hitTestInfo.ColumnIndex == 0)
contextMenuForColumn1.Show(dataGridView,new Point(e.X,e.Y));
// If column is second column
if (hitTestInfo.Type == DataGridViewHitTestType.Cell && hitTestInfo.ColumnIndex == 1)
contextMenuForColumn2.Show(dataGridView,e.Y));
}
}
