calendar控件自动隐藏??

Question

怎么实现:    点到textbox跳出calendar控件,选定一个日期到textbox里 然后 calendar控件自动隐藏起来.

Answer 1

后台代码如下:
protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            Calendar1.Visible = false; //初始日历对象不可看
        }
    }
    protected void TextBox1_TextChanged(object sender, EventArgs e)
    {        Calendar1.Visible = true; //文字改变的时候日历出现
        
    }    protected void Calendar1_SelectionChanged(object sender, EventArgs e)
    {
        TextBox1.Text = Calendar1.SelectedDate.ToShortDateString(); //设置TextBox属性为日历日期
        Calendar1.Visible = false; //日历不可见
    }
刚才运行了一下,输入文字的时候要按回车才能显示日历
请大家帮忙解决一下,在线等,呵呵

Answer 3

我在TextBox中增加了AutoPostBack="true" 可还是要按回车才能显现日历,
请问应该怎么办才能在输入文字或空格什么的时候就出现日历呢

Answer 4

AutoPostBack="true" 的话会在焦点移出TextBox递交表单.你可以自己写javascript来递交表单.

Answer 5

我的代码用了asp.net ajax
http://www.asp.net/ajax/

Answer 6

this.Page.ClientScript.RegisterClientSciptBlock(this.GetType(),"abc",
  yourTextBox.ClientID+".onkeydown='if(this.value=='')"+
  this.Page.GetPostBackEventReference(yourTextBox),
  true);这会让文本控件在内容为空白并开始输入内容时回发触发它的click后台事件。可惜我早已不再开发asp.net程序了。看到csdn的asp.net栏目显示asp.net知识如此比较可惜。你应该去自己研究GetPostBackEventReference背后的理论知识，我不讲解了。

Answer 7

嗯，由于输出的文字本来就在单引号里，需要对单引号进行转义，也就是写this.Page.ClientScript.RegisterClientSciptBlock(this.GetType(),"abc", 
  yourTextBox.ClientID+".onkeydown='if(this.value=='')"+ 
  this.Page.GetPostBackEventReference(yourTextBox).Replace("'","//'"), 
  true); 

Answer 8

可不可以用MouseClick事件
private void textBox1_MouseClick(object sender, MouseEventArgs e)
        {
            this.monthCalendar1.Visible = true;
        }
而不用TextChange事件。

calendar控件在开发过程中一般很少用到,用得最多的是 写个javascript 比喻梅花雪之类
