Hi,

I have a link button as PreviousMonth and a label which displays the present month. So when user clicks on that previousMonth linkbutton,it should display previous month.

For ex,if present month is January and it should be displayed as december when user clicks on previousMonth and if user again clicks on PreviousMonth then it should be displayed as November and so on...........

Can you guys please help me out.


Thanks

推荐答案

您可以使用 DateTime.AddMonths（按钮点击事件）执行此操作） [ ^ ]方法。

这是一个示例代码。

You can do this in the button click event by using the DateTime.AddMonths()[^] method to get the previous month.
Here is a sample code.

DateTime date = DateTime.Now;
date = date.AddMonths(-1);
YourLabelID.Text = string.Format("{0:MMMM}", date);

你可以这样做：



假设在页面加载中你显示当前标签控制月份如下：

You can do this:

Suppose in Page load you show current month in label control as given below :

protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                lblMonth.Text = System.DateTime.Now.ToString("MMM");
            }
        }

您可以在PreviousMonth按钮中写下以下代码点击以获取上个月：

You can write below code in Your "PreviousMonth" button click to get previous month:

protected void btnPreviousMonth_Click(object sender, EventArgs e)
        {
            DateTime tempDate = Convert.ToDateTime("01-"+ lblMonth.Text + "-2013"); 
            lblMonth.Text = tempDate.AddMonths(-1).ToString("MMM");
        }
