使用 Ajax 控件在 asp.net 中使用 AutoSuggest
我正在尝试在 TextBox 中进行自动建议，并且我使用 Ajax 控件来执行此操作。我给电影数组一些值。我想通过使用用户用于登录网站的电子邮件 ID 过滤用户表来从数据库中提供该值。我无法将标签值调用到下面的方法中。我在页面加载期间将用户的电子邮件 ID 存储在标签中。帮助我做到这一点。
[System.Web.Services.WebMethodAttribute(),System.Web.UI.WebControls, System.Web.Script.Services.ScriptMethodAttribute()]
public static string[] GetCompletionList(string prefixText, int count, string contextKey)
{
// Create array of movies
string[] movies = {"Joey", "Joester", "Joker", "Joeic", "Joic", "Shrek II"};
// Return matching movies
return (from m in movies where m.StartsWith(prefixText,StringComparison.CurrentCultureIgnoreCase) select m).Take(count).ToArray();
}
I am trying to do auto suggest in a TextBox and I used Ajax controls to do so. I am giving movies array some values. I want to give that value from the database by filtering the user table with the email Id that the User used to Login to the website. I am not able to call the Label value into the method below. I have stored the email id of user in label during page load. help me to do that.

}

如果您使用的是 AJAX Control Toolkit，您可以在 此处查看示例< /a>.
我不确定标签是什么，但您需要设置
UseContextKey=true;并指定ajaxToolkit:AutoCompleteExtender在您的情况下，您可以添加将以下代码添加到 Page.Load：
If you are using the AJAX Control Toolkit you can see example here.
I am not sure what is the label about, but you need to set
UseContextKey=true;and specify the context key for theajaxToolkit:AutoCompleteExtenderIn your case you can add the following code to Page.Load:
这是因为 web 方法是静态的。加载页面时，将 AutoCompleteExtender 的上下文键设置为标签值（电子邮件 ID）。另外，请确保 UseContextKey 设置为 true。
It's because the web method is static. On the load of your page, set the context key for your AutoCompleteExtender to the label value (email id). Also, make sure that UseContextKey is set to true.
