问题描述
当页面加载时，面板应该被隐藏，点击一个按钮后它应该显示面板但不会发生这种情况......
问题是当页面加载时，面板是隐藏但当我点击按钮时它没有显示面板，即当我点击按钮时没有任何反应。我无法弄明白为什么。
看看我的代码。请告诉我我在哪里犯错，解决方案是什么。
我尝试过：
.aspx： -
When page load the panel should be hidden and after a click on a button it should display the panel but it is not happening like that...
Problem is when the page load ,panel is hidden but when I click on the button it doesn't show the panel i.e. nothing happens when I click on the button. I can't figure out why.
Have a look at my code. Please show me where I am making mistake and what is the solution.
