Hi,
I need RadDatePicker with RequiredFieldValidator. Submitting with no Date shows the errorMessage from RequiredFieldValidator. But I expected to get a red border for DateInput too (InvalidStyle ...). But nothing happens. Whats running wrong?

Hello Heinz,

The RadDatePicker's textbox (which is a RadDateInput control) shows its invalid style only if the user enters something, which cannot be parsed to a valid date. I am afraid that integration between RadDateInput and RequiredFieldValidator, which could exhibit the desired behavior, does not exist.

However, you can use a CustomValidator and trigger the picker's dateinput invalid style manually. Here is a similar example for RadTextBox that will give you an idea what needs to be done:

Hello Heinz,

You can also try the approach by attaching clientclick event for button and check whether the user entered something in RadDatePicker, if yes set the invalid style manually .

ASPX:

    
            <asp:RequiredFieldValidator ID="rfv2" ControlToValidate="RadDatePicker2" runat="server" 
        
                ErrorMessage="RequiredFieldValidator" ></asp:RequiredFieldValidator> 
        
            <telerik:RadDatePicker ID="RadDatePicker2" runat="server" DateInput-InvalidStyle-BackColor="Red"   >  
        
                <DateInput ID="DateInput1" runat="server" >  
        
                <InvalidStyle BackColor="Red" />  
        
                </DateInput>  
        
            </telerik:RadDatePicker> 
        
            <asp:Button ID="Button1" runat="server" Text="Button" OnClientClick="ValidatePicker();" OnClick="Button1_Click" />

JavaScript:

    
            <script type="text/javascript"> 
        
            function ValidatePicker() 
        
            { 
        
                var datepicker = $find("<%= RadDatePicker2.ClientID %>"); 
        
                if(datepicker.get_selectedDate()==null) 
        
                { 
        
                    datepicker.get_dateInput()._textBoxElement.style.border= "red 1px solid";   
        
                } 
        
            } 
        
            </script>

Thanks,
Princy.
