ASP.net(C#),VS2010,Win 7。
WebDev的新手,所以这可能是一个简单的语法,但在这里......
长话短说我必须在GridView上强制回发,它显示我使用ASPxUploadControl上传的附件。我把GridView放在一个ASPxCallbackPanel中,并试图在使用ASPxCallbackPanel.PerformCallback()上传附件后让我的GridView在页面上更新;
这是“上传”控件,其中包含' ClientSideEvent是我尝试从下面显示的Button调用clientSideEvent的地方。只是试图强行按下一个按钮,但我尝试从代码隐藏中做到这一点但是没有用。任何帮助,将不胜感激!
<dxuc:ASPxUploadControl ID="FileUpload1" runat="server"

ShowUploadButton="True"

<ClientSideEvents FileUploadComplete="function(s, e) { Button1.Click; }" />
<%-- <AdvancedModeSettings EnableMultiSelect="True" /> "does not have public property named "advancedModeSettings" version is too old--%>
<ValidationSettings

MaxFileSize="5242880"
FileDoesNotExistErrorText="This file can't be found."

<ErrorStyle ForeColor="Red"/>
</ValidationSettings>
</dxuc:ASPxUploadControl>
这是GridView以及我成功刷新网格的按钮。
<div>

仅供参考:GridView正在获取新的附件。我只是没有在页面上看到它,因为UploadControl只会更新自己。
编辑:想象它只是使用OnClick()方法,如下所示。 DERP。忘了ASPx按钮继承了所有的ASP按钮方法。但是现在我最初制作按钮隐形的计划似乎被挫败了。调用Button1.OnClick()时,Button的Visible属性设置为&#34; false&#34;。它说Button1没有定义。不管怎么说?
<ClientSideEvents FileUploadComplete="function(s, e) { Button1.OnClick(); }" />
答案 0 :(得分:0)
如果我找到了你,你可以通过名为a updateMode 的属性(条件,始终)操纵页面上所有更新面板的行为。如果所有模式都设置为“始终”,则更改一个updatepanel将导致刷新所有内容。
