通过最后选择的第一个取消选择在asp.net中选择/取消选择按钮
我已经动态创建按钮，如代码所示，所有按钮从10:00到12:00，间隔15分钟，并取消选择生命顺序，就像我选择了10：0和10:15然后我不能选择10： 45 ..和ii选择10：0,10：15,10：30,10：45然后我必须取消选择10:15然后我们必须取消选择10:30和10:45 …请帮助我出。
private void GetControls() { count++; for (int i = 10; i < 12; i++) { for (int j = 0; j < 60; j += 15) { Button btn = new Button(); btn.Text = i + "-" + j; btn.ID = i + "-" + j; btn.Command += new CommandEventHandler(this.btn_Click); // btn.Click += btn_Click; flag = true; btn.CommandName = i + "-" + j; if (count==1) { PlaceHolder1.Controls.Add(btn); } } } } private void btn_Click(object sender, CommandEventArgs e) { count++; string ID = (sender as Button).ID; Label1.Text = " Congrates! Your meeting time has been sheduled upto " + ID; Label1.Visible = false; Button btn = sender as Button; if (btn.BackColor == Color.Green) { btn.BackColor = System.Drawing.Color.Yellow; getStatus(sender); } else { btn.BackColor = System.Drawing.Color.Green; } 如果我错了，请纠正我！ 您希望一次只选择一个按钮，这样如果单击一个按钮，其余按钮应该重置？ 如果是这种情况，这里是一个代码：
[编辑]
添加了一个会话以记住动态按钮ID，并使用（。）代替（ – ）按钮ID
private void GetControls() { count++; for (int i = 10; i < 12; i++) { for (int j = 0; j < 60; j += 15) { Button btn = new Button(); btn.Text = i + "-" + j; btn.ID = i + "." + j; btn.Command += new CommandEventHandler(this.btn_Click); // btn.Click += btn_Click; flag = true; btn.CommandName = i + "-" + j; if (count == 1) { PlaceHolder1.Controls.Add(btn); List createdControls = Session["Controls"] != null ? Session["Controls"] as List : new List (); if (!createdControls.Contains(btn.ID)) createdControls.Add(btn.ID); Session["Controls"] = createdControls; } } } }
[已编辑]使用以下内容替换btn-Click事件。
private void btn_Click(object sender, CommandEventArgs e) { count++; string ID = (sender as Button).ID; ResetButton(Convert.ToDouble(ID)); Label1.Text = " Congrates! Your meeting time has been sheduled upto " + ID; Button btn = sender as Button; if (btn.BackColor == Color.Green) { btn.BackColor = System.Drawing.Color.Yellow; } else { btn.BackColor = System.Drawing.Color.Green; } }
[编辑]这是方法实现
private void ResetButton(double selectedButtonID) { List createdControls = Session["Controls"] != null ? Session["Controls"] as List : new List (); TimeSpan timespan = TimeSpan.FromHours(selectedButtonID); string currentSelectedTime = timespan.ToString("h\\:mm"); foreach (string buttonID in createdControls) { if (!string.IsNullOrEmpty(buttonID)) { int comparisonResult = timespan.CompareTo(TimeSpan.FromHours(Convert.ToDouble(buttonID))); Button button = Page.FindControl(buttonID) as Button; if (button != null && comparisonResult==1) { button.BackColor = Color.Yellow;// selected } else { button.BackColor = Color.Red;// deselected } } }
