我有以下updateProgress:
<asp:UpdateProgress ID="UpdateProgress1" runat="server" AssociatedUpdatePanelID="updCampos"
DynamicLayout="true">
<ProgressTemplate>
<div class="carregando">
<span id="sAguarde">Aguarde ...</span> <asp:Image ID="Image1" runat="server" ImageUrl="~/images/loading.gif" />
</div>
</ProgressTemplate>
</asp:UpdateProgress>
.
我需要更改文本后面的代码“aguarde ......”内容,我嵌套在“saguarde”跨度内,但我不知道如何访问这个跨度。语言是C#。
非常感谢您的帮助。
解决方案
只需更改使用标签的<span>
控件,如下所示 -
<asp:Label id="sAguarde" Text="Aguarde ..." runat="server" />
.
并按Codebehind访问它,如下所示 -
Label progressMessageLabel = UpdateProgress1.FindControl("sAguarde") as Label;
if (progressMessageLabel != null)
{
progressMessageLabel.Text = "something";
}
. 其他提示
You could change the span to a serverside control:
<span id="sAguarde" runat="server">Aguarde ...</span>
Then you can access it from the codebehind:
protected override void Render(HtmlTextWriter writer)
{
if (update) // globally declared update boolean to check if the page is being updated
{
HtmlGenericControl sAguarde = (HtmlGenericControl) UpdateProgress1.FindControl("sAguarde");
sAguarde.InnerHTML = "Hi";
}
base.Render(writer);
}
But note that the span's id will be rendered using ASP.NET control naming conventions.
