ASP.NET with jQuery popup dialog: how to post back on dialog closing

由 亡梦爱人 提交于 2019-12-18 17:14:48
问题 Folks, I'm working on a rather complicated site. We have an update panel that contains some controls. When one of the controls is clicked, a jQuery dialog box opens. When the dialog box closes, I want to signal the update panel to change its display. To do that I need to post back to the update panel. I know the dialog box has a handy callback event that you can hook up to. But here's the thing. The javascript that manipulates the dialog is all in a separate .js file. I want to continue

Is there any workaround for the UpdatePanel + Server.Transfer problem?

问题 I'm trying to use an UpdatePanel in my ASP.NET application. Unfortunately, it seems that I can't do this if I am using Server.Transfer() in my application. Modifying that component of the application is not possible - the architecture makes extensive use of Server.Transfer() - in essence, every page request goes through this method. Does any workaround exist for this issue exist? Having to do full-page postbacks is so unfashionable these days... 回答1: I've got it! Thank Og for strange foreign

ASP.NET asynchronous post-back on asp:button click

由 人走茶凉 提交于 2019-12-02 02:03:14
问题 I am using AJAX in asp:net and am trying to handle a situation where an asp:button triggers both a javascript method and a codebehind c# method. To do this I am using onclick and onClientClick attributes for the button. I need a postback to occur for the codebehind to be called however this postback causes the javascript to not work because variables have lost state. Can anyone describe how to handle this? Possible with ajax and async postbacks? It's starting to drive me a bit crazy! Edit:
