我需要知道是否可以在文本框中插入日期，然后在日历中选择该日期。我在 Microsoft Visual Studio Express 2012 for web 中使用日历。
Below is the code for inserting a date into a textbox by selecting the date on the calendar. (However I want to do the opposite)
下面是通过选择日历上的日期将日期插入文本框的代码。（但是我想做相反的事情）

How about
怎么样
protected void TextBox1_TextChanged(object sender, EventArgs e)
{
Calendar1.SelectedDate = Convert.ToDateTime(TextBox1.Text);
}
回答by Kuldeep
protected void LinkButton1_Click(object sender, EventArgs e)
{
if(TextBox1.Text!=string.Empty)
Calendar1.SelectedDate = Convert.ToDateTime(TextBox1.Text);
Calendar1.Visible = true;
}
But you need to validate user eneterd datetime before converting textbox value to datetime. Here is the link of javascript datetime validation.
回答by Schuere
create an event on the Textbox for when the text is changing
在文本更改时在文本框上创建一个事件
Inside the event check wether the text is an actual datetime for handling exceptions
在事件检查中，文本是否是用于处理异常的实际日期时间
protected void TextBox1_TextChanged(object sender, EventArgs e)
{
DateTime curDate = DateTime.Now;
if (DateTime.TryParse(TextBox1.Text, out curDate))
{
Calendar1.SelectedDate = Convert.ToDateTime(TextBox1.Text);
}
}
