如何在不重新加载页面的情况下触发更新面板

Question

Here is the thing:

I have a Master Page, and a couple of other Web Forms. All of them invoke User Controls, and inside the User Controls, there is an Update Panel.

Now that I add a button in the Master Page (all the pages will need that button, that's why it is in the Master Page), I need that button to show a Popup. That's ok.

The problem is that when I click the button, the page rendered again. So I put the button inside an Update Panel and set it as an Async Trigger for the Update Panel.

(imagine something like that: Master page{ update panel { button } content place holder } )

Now the page does not render again, but still launch the Page Load, and that is a problem. If a page takes 5 seconds to show, because it is loading the content, the button in the master page will take 5 seconds too, because it will load all again.

Does someone know something to fix that?

Answer 1

I assume it's an asp.net standard button like

 <asp:Button ID="Button1" runat="server" Text="Button" />

So on click of this button it fires a postback event. But the button needs to show a popup only and if no server code processing is required, better to use

<input type="button" id="Button1" value="Button"/>

Remove UpdatePanel.
