按钮未在 ASP.NET Webforms 中触发

Question

I'm trying to fix a bug I've encountered with a button not triggering in my webform.

The code for the button in the aspx file and the vb file looks like this:

<asp:Button ID="btnUserEditSave" runat="server" Text="Save User" ClientIDMode="Static" CssClass="button saveButton xbtnWaitEvent" width="100px" ToolTip="Save changes" />

Protected Sub btnUserEditSave_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnUserEditSave.Click

I haven't included to code for the button itself as it's irrelevant because the bug relates to the button not triggering rather than the code of the button itself breaking. I've tested how the button works and what causes it to not trigger and here's the information I have thus far:

When first saving user details through this button, the button triggers and all code runs as expected. The page is the reloaded with the new user details showing.

However after doing this, the button will not trigger properly and when clicked will cause the page to go blank. This is despite the fact that no page load methods written in the source trigger either nor does the Javascript seem to either which I've tried testing through the use of alerts (see code below):

if(document.getElementById('btnUserEditSave').clicked == true)
        {
           alert("button was clicked");
        }

It is worth noting that the other buttons on the page also do not work again in a very similar way. The code behind the button does not trigger nor does a page load method trigger. But a blank page is still shown.

If any further code is needed for context then I will provide as much as I can, and any help as to what might be causing this error would be greatly appreciated as I am rather stuck for ideas. Thanks.

您需要在 html 标记中添加 onclick 事件，这就是您连接它的方式。

 <asp:Button ID="btnUserEditSave" onclick="btnUserEditSave_Click" runat="server" Text="Save User" ClientIDMode="Static" CssClass="button saveButton xbtnWaitEvent" width="100px" ToolTip="Save changes" />
