C# – 在ListBox中添加Button（c#list添加元素）

(15)各种Button 与排列 OutlineButton，ButtonBar，Expanded，RaisedButton，StadiumBorder，FlatButton.icon

效果

至于倒数第二行和倒数第一行的效果为啥一样。。可能是fluttersdk升级了。。之前的api不再生效。。算是留坑！

Android:解决ExpandableListView中添加button后item项点击事件问题

在ExpandableListView中添加button后item项不能点击，获取不到点击事件。

原因：

button按钮抢占了ExpandableListView的焦点

解决方法：

为button按钮添加android:focusable=false属性，关闭button获取焦点，ExpandableListView中的项目即可点击

button.addactionlistener(this)_input button

大家好，又见面了，我是你们的朋友全栈君。

//首先要在PageLoad()事件中注册属性 protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { Button1.Attributes.Add(“onclick”, “return checkSame()”);//为Button1添加onclick()事件 ,Button为服务器控件 }//注意：checkSame（）这是一个写在aspx面页的js函数,必须有返回值，为：true 或 false }

//接着写Button1的onclick事件,如果刚才的checkSame（）返回为true则招行下面的事件,否则不执行

protected void Button1_Click(object sender, ImageClickEventArgs e) { sqlParameter[] Params = new sqlParameter[2]; Params[0] = dbs.MakeInParams(“@uid”, sqlDbType.VarChar, 10, Session[“Uid”].ToString()); Params[1] = dbs.MakeOutParms(“@Upwd”, sqlDbType.VarChar, 10); if (dbs.ExecuteNonQuery(CommandType.StoredProcedure, “selectPwd”, Params) > 0) { string userPwd = Params[1].Value.ToString(); if (userPwd != this.old_pwd.Text) { Response.Write(“<script>alert(‘原始密码错误!’)</script>”); } else { } } else { ClientScript.RegisterStartupScript(this.GetType(), “”, “<script>alert(‘操作失败!’)</script>”); }

}

//呵呵。。再写一个js试例吧 function checkSame() { var Obj1=document.getElementById (“new_pwd”).value; var Obj2=document.getElementById (“re_new_pwd”).value; if(Obj1!=Obj2) { alert(“两次密码输入不一致!”); document.getElementById(“new_pwd”).focus(); return false; } else { return true; } }

//明白了吗。。这是一个用来判断两次密码输入是否一致的函数

<script language=”javascript”> <!–

///显示某个订单的详细信息，通过一个模态对话框，而且屏幕会变颜色 function ShowOrderDetails(murl) { // var url = “Alarm_add.aspx?ID=”+ murl +””; var Width=”700″; var Height=”500″; // alert(murl); var vDialog=window.showModalDialog(murl,window,”dialogWidth:” + Width + “px;dialogHeight:” + Height + “px;center:yes;status:no;scroll:yes;help:no;”);

window.location.href =window.location.href; } </script>

protected void Button_add_Click(object sender, EventArgs e) { // Response.Write(“<script language=javascript>location=’AddMenu.aspx’;</script>”); string empno = “”; string url = “Alarm_add.aspx?ID=”+ empno+””; // Button_add.Attributes.Add(“onclick”, “return ShowOrderDetails(‘” + url + “‘)”);//为Button1添加onclick()事件 ,Button为服务器控件 ClientScript.RegisterStartupScript(this.GetType(), “”, “<script>ShowOrderDetails(‘” + url + “‘);</script>”); }
