ValidationSummary不显示错误 [英] ValidationSummary doesn't show Errors

问题描述

我的gridview出现问题，不再显示ValidationSummary错误.会显示ValidationSummary的标题文本，以及在ExpressionValidation触发时设置的*.

I have a problem with my gridview which won't show the ValidationSummary-errors anymore. The Headertext of the ValidationSummary does show up as well as the * which I set to appear whenever the ExpressionValidation fires.

我很确定它以前曾经起作用，但是我不知道为什么它不再起作用了.起初，我认为它可能与页面上的其他GridView有关，因为我在不同的TabPanels中拥有5个不同的GridView，但是我已经为每个GridView创建了一个验证组.

I'm quite sure it worked before, but I don't know why it doesn't anymore. At first I thought it might have something to do with the other GridViews on the page as I have like 5 different GridView in different TabPanels, but I already made one validationgroup per GridView.

如果你们能在这里帮助我，那会很好.我不太清楚问题是什么..也许是UpdatePanel吗?也许我犯了一些愚蠢的错误..?我很笨.

Would be nice if you guys could help me out here. Im not quite sure what the problem is .. maybe it's the UpdatePanel? Maybe I made some dumb mistake ..? I'm rather clueless.

推荐答案

发现了问题..我必须同时为RequiredFieldValidator和RegularExpressionValidator设置错误消息.;)您不需要在文本框btw内添加验证组.

Found The problem .. I have to set the errormessage for both RequiredFieldValidator and RegularExpressionValidator. ;) You don't need the validationgroup inside of the textbox btw.
