右键单击以在 Datagridview 中选择一行并显示一个菜单以将其删除 [英] Right click to select a row in a Datagridview and show a menu to delete it

问题描述

我的 DataGridView 中有几列，而我的行中有数据.我在这里看到的解决方案很少，但我无法组合它们！

I have few columns in my DataGridView, and there is data in my rows. I saw few solutions in here, but I can not combine them!

Simply a way to right-click on a row, it will select the whole row and show a menu with an option to delete the row and when the option selected it will delete the row.

我做了几次尝试，但都没有奏效，而且看起来很乱.我该怎么办?

I made few attempts but none is working and it looks messy. What should I do?

推荐答案

我终于解决了:

• 在 Visual Studio 中，使用名为DeleteRow"的项目创建一个 ContextMenuStrip

• In Visual Studio, create a ContextMenuStrip with an item called "DeleteRow"

然后在 DataGridView 链接 ContextMenuStrip

Then at the DataGridView link the ContextMenuStrip

使用下面的代码帮助我让它工作.

Using the code below helped me getting it work.

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();
}
