无法在Composite控件内实现UpdatePanel控件 [英] Can't implement UpdatePanel control inside Composite control
本文介绍了无法在Composite控件内实现UpdatePanel控件的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
在我的Composite控件中，放置了一个按钮.单击时将显示一个弹出窗口.在弹出窗口中，将有另一个按钮，当单击该按钮时，它将在TextBox中显示文本，等等.我可以显示弹出窗口，但是当在弹出窗口中单击该按钮时，弹出窗口消失了.同样，当我单击第一个按钮时，不显示弹出窗口.所以我想用UpdatePanel包围弹出窗口中的控件，这样就不会发生回发问题.但实际上我搞砸了.到目前为止，无法在Composite控件中实现UpdatePanel.确实，我使用Google太多了.请为我提供完整代码的解决方案.
In my Composite control I placed a button. Which when clicked, a popup will be shown. In the popup there will be another button which when clicked will show text in TextBox and more... I can show popup but when the button is clicked in the popup, the popup vanishes away. Again when I click the first button, the popup is not shown. So I want to surround controls in the popup with UpdatePanel so that no postback problem occurs. But truly I messed up. Can''t implement UpdatePanel in Composite control till now. Truly I used Google too much. Please suggest me a solution with full codes.

推荐答案
(``#div_to_popup'').bPopup({appendTo:``form''，zIndex:2，closeClass:``clickclose' '，modalColor:``White''，modalClose:false，scrollBar:true});返回false;); } 捕获(异常eVal) { lblResult.Text = eVal.ToString(); } } 受保护的重写void RenderContents(HtmlTextWriter writer) { //up.RenderControl(writer); cmdResult.RenderControl(writer); first.RenderControl(writer); text1.RenderControl(writer); ddlist1.RenderControl(writer); text2.RenderControl(writer); lc.RenderControl(writer); lblResult.RenderControl(writer); Button.RenderControl(writer); sec.RenderControl(writer); } 私有void Button_Click(对象发送者，EventArgs e) { TextBox text1 =(TextBox)Controls [2]; text1.Text ="testsucces"; } }
