我正在开发一个 Winforms 应用程序,并且有一个已经绑定到 dataGridView 的对象的 BindingList。
我还有一个“过滤器”文本框,如果它们与文本框文本不匹配,我想从 datagridview 行中过滤掉行。我想以某种方式将文本框连接到一列以隐藏相关行。我怎样才能做到这一点?
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 的评论我已经更新了textBox1_TextChanged
功能并且现在可以正常工作。谢谢拉尔斯科技!
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);
}
}
