Question

当我完成从不同文件夹到网格视图的文件填充时，如何停止我的计时器功能。我成功地从四个不同的文件夹位置获取所有文件，我在网格视图中显示它们。但我不知道何时停止计时器。我的计时器一直在运行。我怎么能阻止这个。

我的代码段：

 private void Form1_Load(object sender, EventArgs e)
    {
        bool authenticated = true;
            if (authenticated == UserInCustomRole(strVal))// && (authenticated &= UserInSystemRole(WindowsBuiltInRole.Administrator)))
            {
                this.button3.Visible = true;
                this.button2.Visible = false;
                timer1.Start();
                filter_table1();
            }

            if (authenticated == UserInCustomRole(strVal1))// && (authenticated &= UserInSystemRole(WindowsBuiltInRole.Administrator)))
            {//
                this.button3.Visible = false;
                this.button2.Visible = true;
                timer1.Start();
                filter_table();
            }

        }  

private void timer1_Tick(object sender, EventArgs e)
    {
        for (int i = 0; i < dataGridView1.Rows.Count; i++)
        {
            //dataGridView1.Rows[i].Cells["Draft Path"].Style = new DataGridViewCellStyle { ForeColor = Color.Blue };
            dataGridView1.Columns["Draft Path"].DefaultCellStyle.Font = new System.Drawing.Font("Microsoft Sans Serif", 8.25F, System.Drawing.FontStyle.Underline, System.Drawing.GraphicsUnit.Point, ((byte)(0)));
            dataGridView1.Columns["Draft Path"].DefaultCellStyle.ForeColor = Color.Blue;

            dataGridView1.Columns["Drawing Path"].DefaultCellStyle.Font = new System.Drawing.Font("Microsoft Sans Serif", 8.25F, System.Drawing.FontStyle.Underline, System.Drawing.GraphicsUnit.Point, ((byte)(0)));
            dataGridView1.Columns["Drawing Path"].DefaultCellStyle.ForeColor = Color.Blue;
            //dataGridView1.Rows[i].Cells["Release Path"].Style = new DataGridViewCellStyle { ForeColor = Color.Blue };
            dataGridView1.Columns["Release Path"].DefaultCellStyle.Font = new System.Drawing.Font("Microsoft Sans Serif", 8.25F, System.Drawing.FontStyle.Underline, System.Drawing.GraphicsUnit.Point, ((byte)(0)));
            dataGridView1.Columns["Release Path"].DefaultCellStyle.ForeColor = Color.Blue;
        }
        dataGridView1.Columns["Archive"].Visible = false;
      //  backgroundWorker1.CancelAsync();
        //this.Opacity = 100;
        bool authenticated = true;
        string textboxGroupName1 = ini.ReadValue("Action", "Fabricator");
        if (authenticated == UserInCustomRole(textboxGroupName1))
        {
            dt.Columns["Drawing Number"].ReadOnly = true;
            dt.Columns["Drawing Path"].ReadOnly = true;
            dt.Columns["Release Path"].ReadOnly = true;
            dt.Columns["Draft Path"].ReadOnly = true;
            dataGridView1.Columns["Error"].Visible = false;
            //dataGridView1.Columns["Archive"].Visible = true;   //making archive visible to the fabricator

        }

        DataGrid dataGrid = new DataGrid();
        int rowCount = dataGridView1.BindingContext[dt].Count;
        label1_status.Text = "Records Found: " + (rowCount).ToString();
         }
    }

如果您将数据绑定到网格，则可以这样做：

private _bindingCompleted = false;
private void dataGridView1_DataBindingComplete(object sender, DataGridViewBindingCompleteEventArgs e)
{
    _bindingCompleted = true;
    // You could also stop timer here if it suits your needs
}

然后在TimerTick事件中检查绑定是否完成：

private void timer1_Tick(object sender, EventArgs e)
{
    if (_bindingCompleted)
        timer1.Stop();

    // Rest of your code
}

一旦我的所有文件都填充在网格视图中，如何停止我的计时器
