过滤通过ListTextField

Question

GridDropDownColumn我实现第一个解决方案： Filtering By ListTextField for GridDropDownColumn

我的代码是：
ASPX

<telerik:GridDropDownColumn DataSourceID="SqlDataSource2" ListTextField="NM_COMUNIDADE" ListValueField="ID_COMUNIDADE" UniqueName="NM_COMUNIDADE_COLUNA" SortExpression="NM_COMUNIDADE" HeaderText="Comunidade" 
DataField="ID_COMUNIDADE"DropDownControlType="RadComboBox" FooterText="" AllowAutomaticLoadOnDemand="false" AutoPostBackOnFilter="true" CurrentFilterFunction="StartsWith" AllowVirtualScrolling="true" 
ShowMoreResultsBox="true" ItemsPerRequest="10" FilterControlWidth="100%" ShowFilterIcon="false" ColumnEditorID="NM_COMUNIDADE_EDITOR"> 
</telerik:GridDropDownColumn> 

<telerik:GridBoundColumn DataField="NM_COMUNIDADE" HeaderText="NM_COMUNIDADE" SortExpression="NM_COMUNIDADE" UniqueName="NM_COMUNIDADE" Display="false" ReadOnly="true"></telerik:GridBoundColumn> 

C＃

protected void gridCultos_ItemCommand(object source, GridCommandEventArgs e) 
{ 
    if (e.CommandName == RadGrid.FilterCommandName) 
    { 
     Pair command = (Pair)e.CommandArgument; 
     if (command.Second.ToString() == "NM_COMUNIDADE_COLUNA") 
     { 
      e.Canceled = true; 
      GridFilteringItem filter = (GridFilteringItem)e.Item; 
      ((filter["NM_COMUNIDADE"].Controls[0]) as TextBox).Text = ((filter["NM_COMUNIDADE_COLUNA"].Controls[0]) as TextBox).Text; 
      command.Second = "NM_COMUNIDADE"; 
      filter.FireCommandEvent("Filter", new Pair(command.First, "NM_COMUNIDADE")); 
     } 
    } 
} 
protected void gridCultos_ItemDataBound(object sender, GridItemEventArgs e) 
{ 
    if (e.Item is GridFilteringItem) 
    { 
     GridFilteringItem item = e.Item as GridFilteringItem; 
     ((item["NM_COMUNIDADE_COLUNA"].Controls[0]) as TextBox).Text = ((item["NM_COMUNIDADE"].Controls[0]) as TextBox).Text; 
    } 
} 

过滤器只工作第一时间与过滤器功能“StartsWith”和它似乎改变后过滤功能“EqualTo”。

的问题是在ASPX：

<telerik:GridDropDownColumn UniqueName="CategoryddColumn" ListTextField="EmployeeID" 
    HeaderText="Category name" ListValueField="OrderID" DataField="OrderID" DataSourceID="SqlDataSource1" 
    AllowVirtualScrolling="true" ShowMoreResultsBox="true" DataType="System.String" 
    ItemsPerRequest="10" FilterControlWidth="100%" ShowFilterIcon="false" FooterText="" 
    AllowAutomaticLoadOnDemand="false" AutoPostBackOnFilter="true"> 
</telerik:GridDropDownColumn> 
<telerik:GridBoundColumn DataField="EmployeeID" UniqueName="EmployeeID" Display="false"> 
</telerik:GridBoundColumn> 

将该溶液设定为GridDropDownColumn数据类型= “System.String” 和除去CurrentFilterFunction = “StartsWith”。该过滤器将与过滤器功能“包含”一起使用，但它是可以的。
