右键单击以选择Datagridview中的行并显示一个菜单以将其删除

Question

我的DataGridView中有几列,并且我的行中有数据.我在这里看到了一些解决方案,但我无法将它们结合起来!

只需右键单击一行,它就会选择整行,并显示一个菜单,其中包含删除行的选项,当选择该选项时,它将删除该行.

我做了一些尝试,但没有一个工作,它看起来很乱.我该怎么办？

Answer 1

我终于解决了它:

• 在Visual Studio中,使用名为"DeleteRow"的项创建ContextMenuStrip

• 然后在DataGridView链接ContextMenuStrip

使用下面的代码帮助我实现了它.

this.MyDataGridView.MouseDown += new System.Windows.Forms.MouseEventHandler(this.MyDataGridView_MouseDown);
this.DeleteRow.Click += new System.EventHandler(this.DeleteRow_Click);

这是很酷的部分

private void MyDataGridView_MouseDown(object sender, MouseEventArgs e)
{
    if(e.Button == MouseButtons.Right)
    {
        var hti = MyDataGridView.HitTest(e.X, e.Y);
        MyDataGridView.ClearSelection();
        MyDataGridView.Rows[hti.RowIndex].Selected = true;
    }
}

private void DeleteRow_Click(object sender, EventArgs e)
{
    Int32 rowToDelete = MyDataGridView.Rows.GetFirstRow(DataGridViewElementStates.Selected);
    MyDataGridView.Rows.RemoveAt(rowToDelete);
    MyDataGridView.ClearSelection();
}

Answer 2

对于这个问题的完整性,最好使用Grid事件而不是鼠标.

首先设置datagrid属性:

SelectionMode到FullRowSelect和RowTemplate/ContextMenuStrip到上下文菜单.

创建CellMouseDown事件: -

private void myDatagridView_CellMouseDown(object sender, DataGridViewCellMouseEventArgs e)
{
    if (e.Button == MouseButtons.Right)
    {
        int rowSelected = e.RowIndex;
        if (e.RowIndex != -1)
        {
            this.myDatagridView.ClearSelection();
            this.myDatagridView.Rows[rowSelected].Selected = true;
        }
        // you now have the selected row with the context menu showing for the user to delete etc.
    }
}

Answer 3

private void dgvOferty_CellContextMenuStripNeeded(object sender, DataGridViewCellContextMenuStripNeededEventArgs e)
    {
        dgvOferty.ClearSelection();
        int rowSelected = e.RowIndex;
        if (e.RowIndex != -1)
        {
            this.dgvOferty.Rows[rowSelected].Selected = true;
        }
        e.ContextMenuStrip = cmstrip;
    }

TADA:D.最简单的方式.对于自定义单元格,只需修改一点.
