DataGridView.DefaultView清除过滤器

如何自动或通过按钮清除应用的过滤器？DataGridView.DefaultView清除过滤器

我使用以下代码来筛选从表格DataGridView从frPlanMain（表格1）2.

using System; 
using System.Collections.Generic; 
using System.ComponentModel; 
using System.Data; 
using System.Drawing; 
using System.Linq; 
using System.Text; 
using System.Threading.Tasks; 
using System.Windows.Forms; 

namespace Plan_de_lucru_1._0 
{ 
    public partial class SearchWindow : Form 
    { 
     public frPlanMain refTofrPlanMain; 

     public SearchWindow(frPlanMain f) //<<Edit made here 
     { 
      refTofrPlanMain = f; 
      InitializeComponent(); 
     } 

     private void SearchButtonW_Click(object sender, EventArgs e) 
     { 
      { 
       (refTofrPlanMain.dGVPlan.DataSource as DataTable).DefaultView.RowFilter = string.Format("Vodic = '{0}'", searchTBoxW.Text); 
       for (int i = refTofrPlanMain.dGVPlan.Rows.Count - 1; i >= 0; i--) 
       { 
        DataGridViewRow item = refTofrPlanMain.dGVPlan.Rows[i]; 
        if (item.Visible) 
        { 
         refTofrPlanMain.dGVPlan.Rows.RemoveAt(i); 
         break;      
        } 
       // 
       } 
       } 
      } 
     } 
    }

你之前问过我o关于如何删除数据，这不是过滤。现在你想要回来的数据？这将需要更多的代码更改... – Draken

好吧，再次感谢您的兴趣。在我删除选定的行后，我想删除过滤器，并看到整个数据源，但没有删除的行。 –

啊，好吧，误解了，看看 – Draken

     private void SearchButtonW_Click(object sender, EventArgs e)

嗯，关于上面的代码，我应该把它放在哪里？ –

根据请求更新了代码，您需要创建一个按钮并将onClick事件添加到方法'clearFilter_onClick'的订阅中 – Draken

要清除一个DataView一个过滤器，设置将其RowFilter属性设置为空字符串

yourDataView.DefaultView.RowFilter = ""
