AJAX AutoComplete Extender在ModalPopUpExtender中不起作用 [英] AJAX AutoComplete Extender Not working in ModalPopUpExtender

问题描述

嗨朋友们，

Hi friends,

AJAX AutoComplete Extender Not working in ModalPopUpExtender

Page方法返回值，但不显示自动完成建议。

The Page method is returning the values but AutoComplete suggestion is not showing.

<asp:TextBox runat="server" ID="txtCity" Width="200px" />
                                                       <Mp:AutoCompleteExtender ID="AutoCompleteExtender1" runat="server" TargetControlID="txtCity"

                                                           MinimumPrefixLength="1" EnableCaching="true" CompletionSetCount="1" CompletionInterval="1000"

                                                           ServiceMethod="SearchCities">
                                                       </Mp:AutoCompleteExtender>

代码背后代码：

Code behind code :

[System.Web.Script.Services.ScriptMethod()]
[System.Web.Services.WebMethod]
public static List<string> SearchCities(string prefixText, int count)
{
    Util utility = new Util();
    List<string> CityList = new List<string>();
    CityList = utility.GetCities(prefixText);
    return CityList;
}

推荐答案

尝试使用 UpdatePanel

在其中放置 TextBox 或模态 PopUp 并设置触发器属性

try using the UpdatePanel
place the TextBox or modal PopUp inside it and set the trigger properties

<asp:updatepanel id="UP1" runat="server" updatemode="Conditional" childrenastriggers="false" xmlns:asp="#unknown">
<triggers>
<asp:asyncpostbacktrigger controlid="txtcity"" eventname="textchange" /></triggers>

大家好

创建如下所述的java脚本函数

Hi All
Create a java script function as mentioned below

function PopupShown(sender, args) {
         sender._popupBehavior._element.style.zIndex = 99999999;
     }

使用属性

use property

OnClientShown="PopupShown" as shown below

<sgg:AutoCompleteExtender ServiceMethod="SearchExpenseHead" MinimumPrefixLength="3"
CompletionListCssClass="AutoCompleteFlyout" CompletionListHighlightedItemCssClass="AutoCompleteFlyoutHilightedItem"
CompletionListItemCssClass="AutoCompleteFlyoutItem" CompletionInterval="10" EnableCaching="false" CompletionSetCount="4" TargetControlID="txtExpenseHead" ID="AutoCompleteExtender1" OnClientShown="PopupShown" runat="server" FirstRowSelected="false"></sgg:AutoCompleteExtender>

必须工作

谢谢

It must work

只需查看代码，我就可以看到冗余代码和简化。您不需要像这样初始化列表，因为列表将由函数的返回值自动填充。



所以这个：

Just looking at your code, I can see redundant code and a simplification. You don't need to initialize the list like that as the list will be automatically filled by the Function's returned values.

So this:

List<string> CityList = new List<string>();
CityList = utility.GetCities(prefixText);
return CityList;

变为：

var CityList = utility.GetCities(prefixText);
return CityList;

并且可以进一步简化：

return utility.GetCities(prefixText);
