我有我的GridView的一个问题，将不会显示在ValidationSummary-错误了。在ValidationSummary的HEADERTEXT并显示以及我设定出现在*每当防爆pressionValidation火灾。

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.

我敢肯定它之前的工作，但我不知道为什么它没有了。起初我以为它可能有一些做的，因为我有一个像5个不同的GridView不同TabPanels页面上的其他GridView的，但我已经制成每GridView控件1的ValidationGroup。

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.

将是很好，如果你们能帮助我在这里。我不是很确定是什么问题..也许这是在UpdatePanel？也许我做了一些愚蠢的错误..？我相当无能。

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

发现问题。我必须设置为的RequiredFieldValidator和RegularEx pressionValidator的errormessage的。 ;）你不需要的文本框BTW内的的ValidationGroup

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.
