Validate Text entered for RadDatePicker control

[Selvaraj]

Hi,

I have a RaddatePicker control and Submit button in my screen . If user chooses date from datepicker, have no issues. If user enters some random characters in dateinput, it shows warning on screen. However, onclick of Submit button, form is being submitted. I want to restrict the form submission. This field is not a required field. So adding required field validator will not help me.
Can anyone please help me in resolving this.

Thanks,

Hi,

One suggestion is that you can handle the OnError event of DateInput and can cancel the form submission. Following is the sample code that I tried to achieve your scenario.

ASPX:

<telerik:RadDatePicker ID="RadDatePicker1" runat="server" DateInput-ClientEvents-OnError="OnError">
</telerik:RadDatePicker>
<asp:HiddenField ID="HiddenField1" runat="server" />
<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" />

JS:

<script type="text/javascript">
    function OnError(sender, args) {
        var err = document.getElementById("HiddenField1");
        err.value = 1;
    }
</script>

C#:

protected void Button1_Click(object sender, EventArgs e)
{
    if (HiddenField1.Value != "1")
    {
        //do the action
    }
}

Hope this helps.
