您好我正在使用telerik radgrid。我正在添加DataSource并将其重新绑定在cs文件中的代码中。
问题是过滤不适用于radgrid。
任何帮助将不胜感激。
由于
<telerik:RadGrid ID="ShopOrderRadGrid" runat="server" GridLines="None" OnItemDataBound="ShopOrderRedGridRadGrid__onItemDataBound" OnItemCommand="ShopOrderRedGridRadGrid_ItemCommand" OnNeedDataSource="ShopOrderRadGrid_NeedDataSource" AllowFilteringByColumn="True" AllowSorting="True" AutoGenerateColumns="False" AllowPaging="True"
PageSize="100">
<MasterTableView AutoGenerateColumns="False" DataKeyNames="ShopOrderId" HierarchyDefaultExpanded="True" CommandItemDisplay="Top" AllowSorting="True" AllowFilteringByColumn="True" AllowCustomSorting="True" ShowFooter="True">
<Columns>
<telerik:GridEditCommandColumn ButtonType="ImageButton" Reorderable="False" Resizable="False"
UniqueName="EditColumn" ShowSortIcon="False">
<HeaderStyle Width="30px" Wrap="False" />
<ItemStyle Width="30px" />
</telerik:GridEditCommandColumn>
<telerik:GridTemplateColumn HeaderText="Print" AllowFiltering="False">
<ItemTemplate>
<asp:Button runat="server" ID="PrintButton" CommandName="Print" Text="Print Order"
OnClientClick="openNewWindow();" />
</ItemTemplate>
<HeaderStyle Width="100px" Wrap="False" />
<ItemStyle Width="100px" />
</telerik:GridTemplateColumn>
<telerik:GridBoundColumn DataField="SimpleCode" HeaderText="Order Code" DataType="System.String"

AllowFiltering="True" ShowFilterIcon="False"

AndCurrentFilterFunction="Contains"
CurrentFilterFunction="Contains">
</telerik:GridBoundColumn>
<telerik:GridTemplateColumn HeaderText="Name" SortExpression="CustomerFirstname"
AllowFiltering="True" ShowFilterIcon="False"
AutoPostBackOnFilter="True"
AndCurrentFilterFunction="Contains"
CurrentFilterFunction="Contains">
<ItemTemplate>
<asp:Label ID="NameLabel" runat="server"></asp:Label>
</ItemTemplate>
</telerik:GridTemplateColumn>
<telerik:GridBoundColumn DataField="TotalCostIncludingTax" HeaderText="Total Cost Including Tax"
SortExpression="TotalCostIncludingTax" ShowFilterIcon="False" UniqueName="TotalCostIncludingTax"
DataFormatString="{0:C}" />
</Columns>
</MasterTableView>
</telerik:RadGrid>

要在代码中应用过滤器，您需要做三件事：
设置过滤器过滤器表达式
RAD_Grid.MasterTableView.FilterExpression = "(Field >= DateTime.Today.AddDays(-14) )" ;
这是网格将过滤的表达式。
设置列电流过滤器
这仅适用于列标题中的过滤器显示。这仅适用于显示和将来的过滤器。必须设置或网格将忽略任何过滤器表达式。您无法过滤列中不存在的数据。即使列已隐藏，您也可以进行过滤。
GridColumn column = RAD_Grid.MasterTableView.GetColumnSafe("Field");
column.CurrentFilterFunction = GridKnownFunction.GreaterThanOrEqualTo ;
column.CurrentFilterValue = DateTime.Today.AddDays(-14).ToShortDateString();
<强>重新绑定
如果您需要一个范围或者您有多个过滤器连接/设置它们在表达式（1。）
如果是初始过滤器，您可以将其设置为aspx。这样就不需要重新绑定了。
EnableLinqExpressions =“true”是文档中以红色显示的重要内容。
注意：
如果使用NeedDataSource事件绑定网格，则可以 在NeedDataSource事件处理程序中设置初始过滤器并省略 调用Rebind方法。设置过滤器的代码必须 仍然被放置在检查它的if语句中 Page.IsPostBack是假的。请注意，这适用于非自动 生成的列。
