右键单击以选中一个DataGridView一行，并显示一个菜单来删除它 [英] Right click to select a row in a Datagridview and show a menu to delete it

问题描述

我在我的DataGridView几列，且有数据在我行。我看到这里几个解决方案，但我不能将它们组合起来！

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!

简单的方式来某行右键点击，它会选择整行，并显示一个菜单选项删除行，当选项选中它会删除行。

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.

我做了一些尝试，但没有工作，它看起来凌乱。我应该怎么办？

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

推荐答案

我终于解决了它：

• 在Visual Studio中，创建一个使用的ContextMenuStrip被称为DeleteRow的项目

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

然后在DataGridView的链接的ContextMenuStrip

Then at the DataGridView link the ContextMenuStrip

使用code下面帮我得到它的工作。

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);

下面是最酷的部分。

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();
}

我希望code可以帮助别人： - ）

I hope the code will help others :-)
