Question

我遇到的问题是我有两组单选按钮。当我在其中任何一个中单击“全部”时，必须禁用SharePoint DatePicker控件并显示自定义日期（如图所示）。但是当你点击第二组radiobuttons时，你看到第一个被启用了。如果你帮我解决这个问题，我将不胜感激。

感谢。

以下是两组单选按钮：

//第一组

 <asp:RadioButton ID="Rd4Month" Text="All" AutoPostBack="True" GroupName="GrpDuration" runat="server" OnCheckedChanged="rdgetDateforMonths" />
  <asp:RadioButton ID="Rd1Month" Text="1 month" AutoPostBack="True" GroupName="GrpDuration" runat="server" OnCheckedChanged="rdgetDateforMonths" />
  <asp:RadioButton ID="Rd2Month" Text="3 month" AutoPostBack="True" GroupName="GrpDuration" runat="server" OnCheckedChanged="rdgetDateforMonths" />
  <asp:RadioButton ID="Rd3Month" Text="6 month" AutoPostBack="True" GroupName="GrpDuration" runat="server" OnCheckedChanged="rdgetDateforMonths" />
  <asp:RadioButton ID="Rd5Month" Text="Other" AutoPostBack="True" GroupName="GrpDuration" runat="server" OnCheckedChanged="rdgetDateforMonths" />

//第二组

<asp:RadioButton ID="Rd4BuildMonth" AutoPostBack="True" Text="All" GroupName="GrpBuildDuration" runat="server" OnCheckedChanged="rdgetBuildDateforMonths" />
 <asp:RadioButton ID="Rd1BuildMonth" AutoPostBack="True" Text="1 month" GroupName="GrpBuildDuration" runat="server" OnCheckedChanged="rdgetBuildDateforMonths" />
 <asp:RadioButton ID="Rd2BuildMonth" AutoPostBack="True" Text="3 month" GroupName="GrpBuildDuration" runat="server" OnCheckedChanged="rdgetBuildDateforMonths" />
  <asp:RadioButton ID="Rd3BuildMonth" AutoPostBack="True" Text="6 month" GroupName="GrpBuildDuration" runat="server" OnCheckedChanged="rdgetBuildDateforMonths" />
  <asp:RadioButton ID="Rd5BuildMonth" AutoPostBack="True" Text="Other" GroupName="GrpBuildDuration" runat="server" OnCheckedChanged="rdgetBuildDateforMonths" />

// SharePoint DateTimeControl

   <table>
   <tr>
   <td style="vertical-align: middle;">
   <asp:Label ID="Label4" runat="server" Text="Start:"></asp:Label>
    </td>
    <td style="vertical-align: middle;">
    <SharePoint:DateTimeControl ID="dtcStartDate" runat="server" DateOnly="True" />
    </td>
    <td style="vertical-align: middle;">
    <asp:Label ID="Label5" runat="server" Text="End:"></asp:Label>
    </td>
    <td style="vertical-align: middle;">
    <SharePoint:DateTimeControl ID="dtcEndDate" runat="server" DateOnly="True" />
    </td>
    </tr>
    </table>

        dtcStartDate.MaxDate = DateTime.Now.AddMonths(-1);
        dtcEndDate.MaxDate = System.DateTime.Today;
        dtcBuildEndDate.MaxDate = System.DateTime.Today; ;

        // When the page loads 1st time

        if (!Page.IsPostBack)
        {

                Rd1Month.Checked = true;
                Rd1BuildMonth.Checked = true;

                dtcBuildEndDate.SelectedDate = System.DateTime.Today;
                dtcStartDate.SelectedDate = DateTime.Now.AddMonths(-1);
                dtcBuildStartDate.SelectedDate = DateTime.Now.AddMonths(-1);
            }

            catch (Exception ex)
            {
                lblErrorMsg.Text += ex.Message;
            }

        }
    }

我将DateTimeControl的Enable修改为False

  <SharePoint:DateTimeControl ID="dtcBuildStartDate" runat="server" DateOnly="True" Enabled="False" />

查看刚刚添加的Page_Load方法并将评论读到我之前的帖子。看起来问题在于共享点日期时间控制的行为方式。您可以尝试添加EnableViewState =“true”。

<SharePoint:DateTimeControl ID="dtcBuildStartDate" runat="server" DateOnly="True" Enabled="False" EnableViewState="true" />

如果未打开viewstate，则每次页面回发时都会重新加载aspx页面定义中的默认值。这也会影响控件的值在回发后不被维护等等。如果enableviewstate不起作用，那么你可以尝试在ViewState中自己添加状态然后在每次回发时你必须管理这个值，但它可能会处理变更等问题变得复杂。

您还可以在页面加载时尝试以下操作：

protected void Page_Load(object sender, EventArgs e)
        {
            //dtcStartDate.MaxDate = System.DateTime.Today;
            dtcBuildStartDate.MaxDate = DateTime.Now.AddMonths(-1);
            dtcStartDate.MaxDate = DateTime.Now.AddMonths(-1);
            dtcEndDate.MaxDate = System.DateTime.Today;
            dtcBuildEndDate.MaxDate = System.DateTime.Today; ;
            lblErrorMsg.Text = "";

            // When the page loads 1st time

            if (!Page.IsPostBack)
            {
                try
                {
                    Rd1Month.Checked = true;
                    Rd1BuildMonth.Checked = true;
                    dtcEndDate.SelectedDate = System.DateTime.Today; // set end date calendar to today's date
                    dtcBuildEndDate.SelectedDate = System.DateTime.Today;
                    dtcStartDate.SelectedDate = DateTime.Now.AddMonths(-1);
                    dtcBuildStartDate.SelectedDate = DateTime.Now.AddMonths(-1);
                }

                catch (Exception ex)
                {
                    lblErrorMsg.Text += ex.Message;
                }

            }

            SetDateBoxEnabled();
        }

        private void SetDateboxEnabled()
        {
            if (Rd4BuildMonth.Checked)
            {
                dtcBuildStartDate.Enabled = false;
            }
            else
            {
                dtcBuildStartDate.Enabled = true;
            }

            if (Rd4Month.Checked)
            {
                dtcStartDate.Enabled = false;
            }
            else
            {
                dtcStartDate.Enabled = true;
            }
        }

在PostBack上启用不同组中的单选按钮
