我试过但它还没来。



请帮忙。

Hi,

I am displaying a calender inside a panel.

And I want to show the calender only when the button is clicked.

I have tried but it's not coming.

Please help.

static int flag = 0;
protected void Page_Load(object sender, EventArgs e)
{
    if (flag == 1)
    {
        pnlCal1.Visible = true;
    }
    if (flag == 0)
    {
        pnlCal1.Visible = false;
    }
    if (!IsPostBack)
    {
        flag = 1;
        pnlCal1.Visible = false;
    }
}
protected void imgDate1_Click(object sender, ImageClickEventArgs e)
{
    pnlCal1.Visible = true;
}

protected void calDate1_SelectionChanged(object sender, EventArgs e)
{
    txtDate1.Text = calDate1.SelectedDate.ToShortDateString();
    //pnlCal1.Visible = false;
    flag = 0;
}

请帮助

推荐答案

       此处您尚未指定您使用的日历（内置日历控件或第三方工具）。但根据你的情况，我认为你正在使用内置的日历控制。

然后你可以这样做。

Hi,
       Here you have not specified which calender you are using(either inbuilt calender control or third party tool). But according to your situation i think you are using inbuilt calender control.
Then you can do it like this.

//design side
//make by default visible false
<asp:Panel ID="pnlCal1" runat="server" Visible="false">
      <asp:Calendar ID="Calendar1" runat="server"></asp:Calendar>
</asp:Panel>
<asp:ImageButton ID="imgDate1" runat="server" OnClick="imgDate1_Click" />

protected void Page_Load(object sender, EventArgs e)
{
    // you don't need to do complex logic here!!!!!
}

protected void imgDate1_Click(object sender, ImageClickEventArgs e)
{
    pnlCal1.Visible = true;  // just make visible here
}

希望它可以帮到你。

谢谢。

Hope it helps you.
Thanks.

Markup:

<asp:Button ID="Button1" runat="server" Text="show panel"

       OnClick="Button1_Click" />
   <asp:Label ID="Label1" runat="server"></asp:Label>
   <asp:Panel ID="Panel1" runat="server" Visible="false">
       <asp:Calendar ID="Calendar1" runat="server" OnSelectionChanged="Calendar1_SelectionChanged">
       </asp:Calendar>
   </asp:Panel>

代码背后：

Code behind:

protected void Button1_Click(object sender, EventArgs e)
    {
        Panel1.Visible = true;
    }
    protected void Calendar1_SelectionChanged(object sender, EventArgs e)
    {
        Panel1.Visible = false;
        Label1.Text = Calendar1.SelectedDate.ToLongDateString();
    }
