i have a regular asp:button. I am working in .Net 3.5. I've tried adding a js confirm to the button with the OnClientClick attribute as well as adding in code-behind and the result is the same. No matter what the user clicks in the confirm pop-up the form will not submit??

BtnDeleteSelected.Attributes.Add("onclick", "return confirm('Are you sure you want to delete?');");

The confirm dialog appears and if i select "OK" it still does not submit.. Any ideas? thanks.

onclick="return confirm('Ok?'); __doPostback();"
的__doPostBack调用由在某些情况下，ASP.NET框架自动插入。既然你返回确认的结果立即无论，回发永远不会触发。最终的解决办法是不要设置onclick属性，而是使用。但是，如果有pressing理由通过的onclick在服务器端控制这一点，你可以用一个简单的如果语句，只有当他们preSS返回取消...
The __doPostback invocation is inserted automatically by the ASP.NET framework in some cases. Since you return immediately regardless of the result of confirm, the postback never fires. The ultimate solution would be to not to set the onclick attribute, but instead use an unobtrusive approach. However, if there is pressing reason to control this on the server-side via onclick, you can use a simple if statement and only return when they press "Cancel"...
string js = "if(!confirm('Are you sure you want to delete?')) return false;";
BtnDeleteSelected.Attributes.Add("onclick", js);
