C# 在中继器网格视图中标记复选框
所以基本上我有两个表，一个是productVariants，一个是DistributionStandardPackingUnitItems。在我的DistributionStandardPackingUnitItems中，它存储要打包的productVariant id和数量。我想做的是，如果产品变量id作为一个项目存在于distributionStandardPackingUnitItems中，那么该行的复选框将被标记。以下是我如何在中继器内设置网格视图：C# 在中继器网格视图中标记复选框,c#,asp.net,repeater,C#,Asp.net,Repeater,所以基本上我有两个表，一个是productVariants，一个是DistributionStandardPackingUnitItems。在我的DistributionStandardPackingUnitItems中，它存储要打包的productVariant id和数量。我想做的是，如果产品变量id作为一个项目存在于distributionStandardPackingUnitItems中，那么该行的复选框将被标记。以下是我如何在中继器内设置网格视图： <asp:Repeater I
