I know because of the postback it's not working. I tried using some javascript onclientclick() . I tried using the updatepanel and updateprogress still no luck.any advice on how this is done.

如果您不希望页面回发，则理想情况下需要使用 JavaScript 执行此操作。

为此，您需要确保元素在页面上但被隐藏，因此不要使用该visible="false"属性，而是使用 cssdisplay: none;指令。

然后用 javascript 显示它，使用您选择的库选择它并显示它。例如，使用 jquery -$('selector').show()
