用户控件在IE8版本中不起作用 [英] Usercontrol is not working in IE8 Version

问题描述

在我的应用程序中，我创建了一个web usercontrol可编辑下拉列表。它在Mozilla Firefox中工作。但是客户端要求应用程序只能兼容IE8版本。但它在IE 8中无效。我们无法在IE8中选择选项。我们如何解决这个问题？



我把css放在这个地方的控制中。我用ui-widget类的jquery-ui.css文件。



是否有任何选项可以改变IE8版本的版本兼容性。

In my application I have created one web usercontrol Editable dropdownlist. It is working in mozilla firefox. But the client asks that application should compatability only IE8 Version. But it is not worked in IE 8.We can't select option in IE8. How we solve this problem?

I put css in that control this place. I am used jquery-ui.css file for ui-widget class.

Is there any option to change version compatability for IE8 version.

推荐答案

（＃{0}）。组合框（{{来源：{1}，名称：{2}，autopostback：{3}，autoselectFirstItem：{4}}}）;，baseID，userSelections，listID，（AutoPostBack | | OnClick！= null ）。ToString（）。ToLower（），AutoselectFirstItem.ToString（）。ToLower（））;

// 检查我们是否需要关注我们的组合框
if （_ setFocus）
{
script + = string .Format（ \ n

(""#{0}"").combobox( {{source: {1}, name: ""{2}"", autopostback: {3}, autoselectFirstItem: {4}}} );", baseID, userSelections, listID, (AutoPostBack || OnClick != null).ToString().ToLower(), AutoselectFirstItem.ToString().ToLower()); // Check if we need to set focus on our combobox if (_setFocus) { script += string.Format("\n

（\＃{0} \）。focus（）;，listID）;
}

if （ScriptManager.GetCurrent（ this .Page） ！= null ）
ScriptManager.RegisterStartupScript（ this ， this .GetType（）， init + ClientID，script，真）;
else
this .Page.ClientScript.RegisterStartupScript（ this .GetType（）， init + ClientID，脚本， true ）;
}
