我正在尝试获取必要的字段验证,以便在单击添加按钮时仅为特定行触发。但是现在,当我单击任何添加按钮时,它会触发所有嵌套网格行的必需字段验证。嵌套网格视图的代码和网格视图的图像如下。我还尝试使用验证组,尝试为每个嵌套的gridview行获取唯一的验证组,但无法使其工作。

答案 0 :(得分:0)
对于每行的验证控件,您要添加ValidationGroup ='&lt;%#“PC”+ Eval(“ContractProjectCodeID”)%&gt;'。正如您所说,验证触发错误的行,可能是ContractProjectCodeID对于每一行可能不是唯一的。我认为您可以做的是将行索引添加到验证组
ValidationGroup='<%# "PC" + Container.DataItemIndex + Eval("ContractProjectCodeID")
