Validation in CalendarExtender

Example



Adding CompareValidator
<asp:CompareValidator ID="CompareValidator1" runat="server"
                ControlToValidate="TextBox1" Display="Dynamic" ErrorMessage="Invalid Date"
                Operator="DataTypeCheck" Type="Date">
</asp:CompareValidator>
<cc1:ValidatorCalloutExtender ID="CompareValidator1_ValidatorCalloutExtender"
                runat="server" Enabled="True" TargetControlID="CompareValidator1">
</cc1:ValidatorCalloutExtender>
Adding RangeValidator – We will restrict the user to select a date range starting from today to 15 days from now.
<asp:RangeValidator ID="RangeValidator1" runat="server"
                ControlToValidate="TextBox1" ErrorMessage="RangeValidator"
                Type="Date">
</asp:RangeValidator>
<cc1:ValidatorCalloutExtender ID="RangeValidator1_ValidatorCalloutExtender"
                runat="server" Enabled="True" TargetControlID="RangeValidator1">
</cc1:ValidatorCalloutExtender>
 
In the code behind of your page, add this code
C#
    protected void Page_Load(object sender, EventArgs e)
    {
        RangeValidator1.MinimumValue = System.DateTime.Now.ToShortDateString();
        RangeValidator1.MaximumValue = System.DateTime.Now.AddDays(15).ToShortDateString();
    }
VB.NET
      Protected Sub Page_Load(ByVal sender As ObjectByVal e As EventArgs)
            RangeValidator1.MinimumValue = System.DateTime.Now.ToShortDateString()
            RangeValidator1.MaximumValue = System.DateTime.Now.AddDays(15).ToShortDateString()
      End Sub
