Question

我正在使用Winforms应用程序，我有一个已绑定到dataGridView的对象的BindingList。
我还有一个＆＃34; Filter＆＃34;我想要从datagridview行中过滤行的文本框，如果它们与文本框文本不匹配。我想以某种方式将文本框连接到列以隐藏相关的行。我怎么能这样做？

所以这是代码：

public partial class Form1 : Form
{

    BindingList<SWItem> blist = new BindingList<SWItem>();

    public Form1()
    {
        InitializeComponent();

        dataGridView1.AutoGenerateColumns = false;
        this.ServerName.DataPropertyName = "ServerName";
        this.SoftwareName.DataPropertyName = "SoftwareName";

        dataGridView1.DataSource = blist;

        blist.Add(new SWItem("item1", "bla"));
        blist.Add(new SWItem("item2", "bla"));
        blist.Add(new SWItem("item3", "bla"));
    }

    private void textBox1_TextChanged(object sender, EventArgs e)
    {
        try
        {
            string Filter = string.Format("ServerName like '%{0}%'", textBox1.Text.Trim().Replace("'", "''"));
            (dataGridView1.DataSource as DataTable).DefaultView.RowFilter = Filter;
        }
        catch (Exception ex)
        {
            new ToolTip().SetToolTip(textBox1, ex.Message);
        }
    }
}

public class SWItem
{
    public string ServerName { get; set; }
    public string SoftwareName { get; set; }

    public SWItem(string ServerName_, string SoftwareName_)
    {
        ServerName = ServerName_;
        SoftwareName = SoftwareName_;
    }
}

根据LarsTech的评论，我更新了textBox1_TextChanged功能，现在它正常运行。谢谢LarsTech！

private void textBox1_TextChanged(object sender, EventArgs e)
{
    try
    {
        string Filter = textBox1.Text.Trim().Replace("'", "''");
        dataGridView1.DataSource = new BindingList<SWItem>(blist.Where(m => m.ServerName.Contains(Filter)).ToList<SWItem>());
    }
    catch (Exception ex)
    {
        new ToolTip().SetToolTip(textBox1, ex.Message);
    }
}

将dataGridView绑定到bindinglist并按文本框过滤行
