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
Manasa

推荐答案

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

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");
        }
