问题描述
我已经动态创建按钮，如在代码中所有的所有按钮，从10:00到12:00与间隔15分钟，就像如果我选择了10取消LIFO顺序：0和10:15那我就不能选择10:45 ..和II已选择10：0,10：15,10：30,10：45，然后我不得不取消10:15那么首先我们要取消10:30和10:45 ... 。请帮我
私人无效的GetControls（）

计数++;
的for（int i = 10; I< 12;我++）
{
为（INT J = 0; J< 60; J + = 15）
{
键BTN =新按钮（）;
btn.Text = I + - + J;
btn.ID = I + - + J;
btn.Command + =新CommandEventHandler（this.btn_Click）;
// btn.Click + = btn_Click;
标志= TRUE;
btn.CommandName = I + - + J;
如果（计数== 1）
{
PlaceHolder1.Controls.Add（BTN）;
}
}
}
}

键BTN =发件人的按钮;
如果（btn.BackColor == Color.Green）
{
btn.BackColor = System.Drawing.Color.Yellow;
的getStatus（寄件人）;
}
，否则
{
btn.BackColor = System.Drawing.Color.Green;
}
解决方案
纠正我，如果我错了！你想每次只选择一个按钮，如果单击一个按钮，剩下的应该重置？如果是这样的话，这里有一个代码，这样做的：
添加一个Session记住动态按钮标识和使用，而不是（）（ - ）的按钮IDS
私人无效的GetControls（）
{
计数++;
的for（int i = 10; I< 12;我++）
{
为（INT J = 0; J< 60; J + = 15）
{
键BTN =新按钮（）;
btn.Text = I + - + J;
btn.ID = I +。 + j的;
btn.Command + =新CommandEventHandler（this.btn_Click）;
// btn.Click + = btn_Click;
标志= TRUE;
btn.CommandName = I + - + J;
如果（计数== 1）
{
PlaceHolder1.Controls.Add（BTN）;
名单，LT;字符串> createdControls =会话[控制]！= NULL？会话[控件]作为名单<串GT;新名单<串GT;（）;
如果createdControls.Add（btn.ID）（createdControls.Contains（btn.ID）！）;
会话[控件] = createdControls;
}
}
}
}
替换为以下的BTN-Click事件。
私人无效btn_Click（对象发件人，CommandEventArgs E）
{
计数++;
字符串ID =（发件人为按钮）.ID;
ResetButton（Convert.ToDouble（ID））;
Label1.Text =！Congrates您的会议时间已经sheduled高达+ ID;
键BTN =发件人的按钮;
如果（btn.BackColor == Color.Green）
{
btn.BackColor = System.Drawing.Color.Yellow;
}
，否则
{
btn.BackColor = System.Drawing.Color.Green;
}
}
这是方法实施
私人无效ResetButton（双selectedButtonID）
{
名单<串> createdControls =会话[控制]！= NULL？会话[控件]作为名单<串GT;新名单<串GT;（）;
时间跨度时间跨度= TimeSpan.FromHours（selectedButtonID）;
串currentSelectedTime = timespan.ToString（h\\：毫米）;
的foreach（字符串buttonID在createdControls）
{
如果（！string.IsNullOrEmpty（buttonID））
{
INT comparisonResult = timespan.CompareTo（TimeSpan.FromHours（ Convert.ToDouble（buttonID）））;
按钮= Page.FindControl（buttonID）的按钮;
如果（键= NULL&放大器;！&安培; comparisonResult == 1）
{
button.BackColor = Color.Yellow; //选择
}
$其他b $ b {
button.BackColor = Color.Red; //取消
}
}
}
I have dynamically created buttons as shown in code all all the button from 10:00 to 12:00 with 15 min of interval and deselect in lifo order like if i have selected 10:0 and 10:15 then i can not select 10:45 .. and i i have selected 10:0,10:15,10:30,10:45 and then i have to deselect 10:15 then first we have to deselect 10:30 and 10:45 ...please help me out.
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;
}
解决方案
Correct me if I am wrong! You want to only select one button at a time so that if one button is clicked, the rest should reset? if that's the case, here's a code to do so:
[Edit]
Added a Session to remember dynamic button ids and used (.) instead of (-) for button Ids
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<string> createdControls = Session["Controls"] != null ? Session["Controls"] as List<string> : new List<string>();
if (!createdControls.Contains(btn.ID)) createdControls.Add(btn.ID);
Session["Controls"] = createdControls;
}
}
}
}
[Edited] Replace the btn-Click event with the following.
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;
}
}
[Edited] And this is the method implementation
private void ResetButton(double selectedButtonID)
{
List<string> createdControls = Session["Controls"] != null ? Session["Controls"] as List<string> : new List<string>();
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
}
}
}
