如何在DataGridView的列中添加按钮 [英] How to add a button to a column in the DataGridView

问题描述

DataTable dt = new DataTable();
dt.Columns.Add(new DataColumn("Software Title", typeof(string)));
dt.Columns.Add(new DataColumn("Version", typeof(string)));
dt.Columns.Add(new DataColumn("Uninstall", typeof(System.Windows.Forms.Button)));

DataRow dr = dt.NewRow();
dr[0] = "App";
dr[1] = "1.0";
Button uninstall = new Button();
uninstall.Text = "Uninstall";

dr[2] = uninstall;

dt.Rows.Add(dr);

dataGridViewSoftware.DataSource = dt;

文本显示，但按钮不显示。

The text appears but button never shows up.

推荐答案

假设您在Windows窗体中，您需要在 DataGridView c中添加一个 DataGridViewButtonColumn code> - 不直接到 DataTable 。

Assuming you are in Windows Forms, you need to add a DataGridViewButtonColumn to your DataGridView - Not directly to the DataTable.

这应该发生在绑定 DataTable 到 DataGridView 。

这样的东西应该有效：

Something like this should work:

DataGridViewButtonColumn uninstallButtonColumn = new DataGridViewButtonColumn();
uninstallButtonColumn.Name = "uninstall_column";
uninstallButtonColumn.Text = "Uninstall";
int columnIndex = 2;
if (dataGridViewSoftware.Columns["uninstall_column"] == null)
{
    dataGridViewSoftware.Columns.Insert(columnIndex, uninstallButtonColumn);
}

当然，你必须处理 CellClick 事件的网格做任何事情的按钮。

Of course you will have to handle the CellClick event of the grid to do anything with the button.

将其添加到您的DataGridView初始化代码中的某个位置

Add this somewhere in your DataGridView Initialization code

dataGridViewSoftware.CellClick += dataGridViewSoftware_CellClick;

然后创建处理程序：

private void dataGridViewSoftware_CellClick(object sender, DataGridViewCellEventArgs e)
{
    if (e.ColumnIndex == dataGridViewSoftware.Columns["uninstall_column"].Index)
    {
        //Do something with your button.
    }
}
