更改DataGridViewButtonColumn中按钮的文本值 [英] Change the text value of a button in DataGridViewButtonColumn

问题描述

每次尝试单击按钮时，我都试图更改DataGridViewButtonColumn中按钮的文本.

I'm trying to change the text of a button in a DataGridViewButtonColumn every time the button is clicked.

我这样定义列:

DataGridViewButtonColumn sitemapButtonColumn = new DataGridViewButtonColumn
{
     Name = "Process",
     Text = "Start",
     UseColumnTextForButtonValue = true,
     DataPropertyName = "Process",
     FillWeight = 7,
     Width = 75
};
dg_list.CellContentClick += dg_list_StartStopProcessClick;

现在，单击单元格后控制事件的功能是:

Now the function which controls the event once a cell clicked is:

private void dg_list_StartStopProcessClick(object sender, DataGridViewCellEventArgs e)
        {
            var senderGrid = (DataGridView)sender;
            if (senderGrid.Columns[e.ColumnIndex] is DataGridViewButtonColumn &&
                e.RowIndex >= 0 &&
                e.ColumnIndex == dg_lista_blogs_automatizacion.Columns["Process"].Index)
            {
                if (senderGrid.Rows[e.RowIndex].Cells[e.ColumnIndex].Value.ToString() == "Start")
                {
                    senderGrid.Rows[e.RowIndex].Cells[e.ColumnIndex].Value = "Stop";
                    senderGrid.Rows[e.RowIndex].Cells[e.ColumnIndex].Style.BackColor = Color.OrangeRed;
                }
                else
                {
                    senderGrid.Rows[e.RowIndex].Cells[e.ColumnIndex].Value = "Start";
                    senderGrid.Rows[e.RowIndex].Cells[e.ColumnIndex].Style.BackColor = Color.White;
                }
            }
        }

嗯，这行不通！

我一直在搜索，发现有一条帖子将UseColumnTextForButtonValue修改为false，设置了新的文本值，然后再次设置为true.

I've been googling and found a post which modifies UseColumnTextForButtonValue to false, set the new text value and set to true again.

问题是我无法弄清楚如何在事件中访问 UseColumnTextForButtonValue 属性.

The problem is that i can not figure out how can i get access to UseColumnTextForButtonValue property within the event.

有帮助吗?

推荐答案

基本上，我可以解决在 DataGridViewButtonColumn 实例中将 UseColumnTextForButtonValue 设置为false的问题.

Basically, i could solve the problem setting UseColumnTextForButtonValue to false in the DataGridViewButtonColumn instance.

将 UseColumnTextForButtonValue 设置为false时，必须在其他情况下初始化按钮的文本值.因此，我使用 CellFormatting 事件根据我想要的状态设置文本值.

When UseColumnTextForButtonValue is set to false, the text value of the button must be initied in other event. So, i use CellFormatting event for setting the text value according to the state I desire.

private void dg_list_auto_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
        {
            if (e!=null && e.ColumnIndex==0)
            {
                dg_list_auto.Rows[e.RowIndex].Cells[0].Value = dg_list_auto[e.RowIndex].flag_sitemap_started?"Stop":"Start";
                dg_list_auto.Rows[e.RowIndex].Cells[0].Style.BackColor = dg_list_auto[e.RowIndex].flag_sitemap_started ? Color.IndianRed: Color.GreenYellow;
            }
        }
