Hi,
How can i use a range validator to select any of the dates between the current date and next 30 dates after the current date and dates previous to current date should not be selected.can any one plz suggest some sample codes?

推荐答案

您好，您应该在页面加载事件中设置范围验证属性：

Hi for this you should set range validation property in page load event:

RangeValidator1.MinimumValue = DateTime.Now.Date.ToString("dd-MM-yy");
  RangeValidator1.MaximumValue = DateTime.Now.Date.AddDays(30).ToString("dd-MM-yy");

您可以按照以下方式进行验证。



在Aspx页面

Hi you can do as below to get validation.

In Aspx page

<tr>
     <td>
       <asp:TextBox ID="txtvalue" runat="server"></asp:TextBox>
       <asp:RangeValidator ID="Rvalid" runat="server"

ControlToValidate="txtvalue" ValidationGroup="Submit" ErrorMessage="your message"></asp:RangeValidator>
   </td>
</tr>
<tr>
   <td>
       <asp:Button ID="buttonclick"

ValidationGroup="Submit" runat="server" Text="Submit"

                         onclick="buttonclick_Click" />

   </td>
</tr>

在页面上加载CS页面

In CS page on page load

protected void Page_Load(object sender, EventArgs e)
         {
             Rvalid.MinimumValue = DateTime.Now.Date.ToString("MM-dd-yyyy");
             Rvalid.MaximumValue =
DateTime.Now.Date.AddDays(30).ToString("MM-dd-yyyy");
         }

希望这会对你有所帮助.... :) >
