RadDatePicker: How to pass invalid date to server for validation

[Shubh]

Previous Question

I am trying to validate date in server side. When I am trying to pass invalid date to my server side code, it is getting converted to {01/01/0001 00:00:00}.

Works fine when I select proper date.

Here is my code:

<telerik:RadDatePicker ID="rdpDob" runat="server" AutoPostBack="true"   DateInput-EmptyMessage="MaxDate" MinDate="01/01/1000"MaxDate="01/01/3000">

When I try to access the date value:

rdpDob.SelectedDate

It is returning as null.

Which is quiet strange as I can see my invalid date being passed in the POST request.

Whats wrong with what I am doing, Is there any property which I need to tweek??

Thanks.

Hi Shubh,

InValidDate will not be available after postback. One suggestion is that you can use the InvalidTextBoxValue  property. Please have a look into the sample code snippet.

ASPX:

<telerik:RadDatePicker ID="RadDatePicker1" runat="server" MinDate="01/01/2014">
</telerik:RadDatePicker>
<telerik:RadButton ID="RadButton1" runat="server" Text="Validate" OnClick="RadButton1_Click">
</telerik:RadButton>

C#:

protected void RadButton1_Click(object sender, EventArgs e)
{
    string value=RadDatePicker1.DateInput.InvalidTextBoxValue;
    if (value != string.Empty)
    {
        //your code for validation
    }
}

Thanks,
Shinu.
