Question

我为txtProjectDate文本框启用了必需的字段验证器，在单击日历按钮后不允许日历加速。因此，我无法选择要输入到文本框的值。错误：必填字段

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>

ASPX.CS CODES FOR textbox，calendar，button

  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;
        }

请帮我找出解决方案......

只需在claims中将CausesValidation属性设置为false： -

ImageButton

从日历中选择后，值不会进入文本框
