定製日期colmn telerik電網的過濾器選項

我正在使用telerik電網。我需要爲網格中的所有列應用過濾器。當然，我正在使用下面的代碼自定義篩選器選項。通過使用以下代碼，我將刪除所有列的某些項目。但是，對於日期列，任何人都可以告訴我在網格中過濾的可能選項以及如何自定義這些過濾選項？定製日期colmn telerik電網的過濾器選項

代碼隱藏

protected void RGVTest_Init(object sender, EventArgs e) 
    { 

     GridFilterMenu menu = RGVTest.FilterMenu; 
     int i = 0; 
     while (i < menu.Items.Count) 
     { 
      if (menu.Items[i].Text == "Between" || 
       menu.Items[i].Text == "NotBetween") 
      { 
       menu.Items.RemoveAt(i); 
      } 
      else 
      { 
       i++; 
      } 
     } 
    }

你不喜歡這種方式：

protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e) 
{ 
    if (e.CommandName == RadGrid.FilterCommandName) 
    { 
     Pair filterPair = e.CommandArgument as Pair; 
     string columnName = Convert.ToString(filterPair.Second); 
     if (columnName == "CreationDate") 
     { 
      e.Canceled = true; 
      string date = ((TextBox)((GridFilteringItem)e.Item)[Convert.ToString(filterPair.Second)].Controls   [0]).Text; 
      DateTime startDate = Convert.ToDateTime(date); 
      DateTime endDate = startDate.AddDays(1); 
      string newFilter = "('" + startDate.ToString("MM/dd/yyyy") + "' <= [CreationDate] AND [CreationDate] <= '"   + endDate.ToString("MM/dd/yyyy") + "')"; 
      GridBoundColumn dateColumn = (GridBoundColumn)e.Item.OwnerTableView.GetColumnSafe(columnName); 
      dateColumn.CurrentFilterValue = startDate.ToString("MM/dd/yyyy"); 
      RadGrid1.MasterTableView.FilterExpression = newFilter; 
      RadGrid1.Rebind(); 
     } 
    } 
}

嘗試這樣

function FilterMenuShowing(sender, eventArgs) 
    {  
     if (eventArgs.get_column().get_uniqueName() == "IsPostable")  
     {    
      var menu = eventArgs.get_menu(); 
      var items = menu._itemData; 

      var i = 0; 

      while (i < items.length)  
      {  
       if (items[i].value != "NoFilter" && items[i].value != "EqualTo" && items[i].value != "NotEqualTo")  
       {  
        var item = menu._findItemByValue(items[i].value); 
        if (item != null) 
         item._element.style.display="none"; 
       }  
       i++;  
      } 
     } 
     else 
     { 
      var menu = eventArgs.get_menu(); 
      var items = menu._itemData; 

      var i = 0; 
      while (i < items.length)  
      {  
       var item = menu._findItemByValue(items[i].value); 
       if (item != null) 
        item._element.style.display=""; 
       i++;  
      } 
     }  

    }

在網格上添加 -

<ClientSettings> 
    <ClientEvents OnFilterMenuShowing="filterMenuShowing" /> 
</ClientSettings>

You can try the way its done below for "order date" column. 

protected void RadGrid1_ItemCommand(object source, Telerik.Web.UI.GridCommandEventArgs e) 
{ 
    if (e.CommandName == RadGrid.FilterCommandName && 
    ((Pair)e.CommandArgument).Second.ToString() == "OrderDate" 
    && 
    ((Pair)e.CommandArgument).First != "NoFilter") 
    { 
     e.Canceled = true; 
     GridFilteringItem filterItem = (GridFilteringItem)e.Item; 
     string currentPattern = (filterItem[((Pair)e.CommandArgument).Second.ToString()].Controls[0] as TextBox).Text; 
     string filterPattern = ""; 
     string filterPatternAssist = ""; 
     if (currentPattern.IndexOf(" ") != -1) 
     { 
      currentPattern = currentPattern.Replace(" ", "/"); 
     } 
     string[] vals = currentPattern.Split("/".ToCharArray()); 
     string filterOption = (e.CommandArgument as Pair).First.ToString(); 
     if (filterOption != "IsNull" && filterOption != "NotIsNull") 
     { 
      if (vals.Length > 3) 
      { 
       filterPatternAssist = vals[4] + "/" + vals[3] + "/" + vals[5]; 
      } 
      filterPattern = vals[1] + "/" + vals[0] + "/" + vals[2]; 
     } 
     GridBoundColumn dateColumn = (GridBoundColumn)e.Item.OwnerTableView.GetColumnSafe("OrderDate"); 
     switch (filterOption) 
     { 
      case "EqualTo": 
       filterPattern = "[OrderDate] = '" + filterPattern + "'"; 
       dateColumn.CurrentFilterFunction = GridKnownFunction.EqualTo; 
       break; 
      case "NotEqualTo": 
       filterPattern = "Not [OrderDate] = '" + filterPattern + "'"; 
       dateColumn.CurrentFilterFunction = GridKnownFunction.NotEqualTo; 
       break; 
      case "GreaterThan": 
       filterPattern = "[OrderDate] > '" + filterPattern + "'"; 
       dateColumn.CurrentFilterFunction = GridKnownFunction.GreaterThan; 
       break; 
      case "LessThan": 
       filterPattern = "[OrderDate] < '" + filterPattern + "'"; 
       dateColumn.CurrentFilterFunction = GridKnownFunction.LessThan; 
       break; 
      case "GreaterThanOrEqualTo": 
       filterPattern = "[OrderDate] >= '" + filterPattern + "'"; 
       dateColumn.CurrentFilterFunction = GridKnownFunction.GreaterThanOrEqualTo; 
       break; 
      case "LessThanOrEqualTo": 
       filterPattern = "[OrderDate] <= '" + filterPattern + "'"; 
       dateColumn.CurrentFilterFunction = GridKnownFunction.LessThanOrEqualTo; 
       break; 
      case "Between": 
       filterPattern = "'" + filterPattern + "' <= [OrderDate] AND [OrderDate] <= '" + filterPatternAssist + "'"; 
       dateColumn.CurrentFilterFunction = GridKnownFunction.Between; 
       break; 
      case "NotBetween": 
       filterPattern = "[OrderDate] <= '" + filterPattern + "' OR [OrderDate] >= '" + filterPatternAssist + "'"; 
       dateColumn.CurrentFilterFunction = GridKnownFunction.NotBetween; 
       break; 
      case "IsNull": 
       break; 
      case "NotIsNull": 
       break; 
     } 
     foreach (GridColumn column in RadGrid1.MasterTableView.Columns) 
     { 
      if (column.UniqueName != "OrderDate") 
      { 
       column.CurrentFilterFunction = GridKnownFunction.NoFilter; 
       column.CurrentFilterValue = string.Empty; 
      } 
     } 
     Session["filterPattern"] = filterPattern; 
     dateColumn.CurrentFilterValue = currentPattern; 
     filterItem.OwnerTableView.Rebind(); 
    } 
    //Add more conditional checks for commands here if necessary 
    else if (e.CommandName != RadGrid.SortCommandName && e.CommandName != RadGrid.PageCommandName) 
    { 
     Session["filterPattern"] = null; 
     GridBoundColumn dateColumn = (GridBoundColumn)e.Item.OwnerTableView.GetColumnSafe("OrderDate"); 
     dateColumn.CurrentFilterFunction = GridKnownFunction.NoFilter; 
     dateColumn.CurrentFilterValue = string.Empty; 
    } 
}
