从日历中进行选择后，值没有输入到文本框中

本文关键字：输入 文本 日历 行选 选择 | 更新日期: 2023-09-27 18:15:16

我已经为txtProjectDate文本框启用了必填字段验证器，它不允许在单击日历按钮后弹出日历。因此，无法在文本框中选择要输入的值。错误:强制性字段

ASPX文件
 <tr>
            <td>Project Started at</td>
            <td>::</td>
            <td><asp:TextBox ID="txtProjectDate" runat="server" OnTextChanged="txtProjectDate_TextChanged1"></asp:TextBox>
               <asp:ImageButton ID="btnShowCalendar" runat="server" OnClick="btnShowCalendar_Click" ImageUrl="D:'calendar4.png" />
               <asp:Calendar ID="calProjectDate" runat="server" OnSelectionChanged="calProjectDate_SelectionChanged" Visible="False"></asp:Calendar>
               <asp:RequiredFieldValidator ID="rfvProjectDate" runat="server" ControlToValidate="txtProjectDate" ErrorMessage="MANDATORY"></asp:RequiredFieldValidator>
              </td>
        </tr>

文本框、日历、按钮的asp . cs代码

  protected void btnShowCalendar_Click(object sender, ImageClickEventArgs e)
        {
            calProjectDate.Visible = true;
        }
        protected void calDateofBirth_SelectionChanged(object sender, EventArgs e)
        {
            txtProjectDate.Text = calProjectDate.SelectedDate.ToShortDateString();
            calProjectDate.Visible = false;
        }
        protected void txtProjectDate_TextChanged(object sender, EventArgs e)
        {
        }
        protected void calProjectDate_SelectionChanged(object sender, EventArgs e)
        {
            txtProjectDate.Text =
            calProjectDate.SelectedDate.ToShortDateString();
            calProjectDate.Visible = false;
        }

从日历中进行选择后，值没有输入到文本框中

将ImageButton中的CausesValidation属性设置为false:-

 <asp:ImageButton ID="btnShowCalendar" runat="server" CausesValidation="false" 
       OnClick="btnShowCalendar_Click" ImageUrl="D:'calendar4.png" />
