Hi Rahul,

Please have a look into the full code that I tried which works fine at my end.

ASPX:

<telerik:RadDatePicker ID="RadDatePicker1" runat="server">
</telerik:RadDatePicker>
<telerik:RadButton ID="RadButton1" Text="Clear" runat="server" OnClick="RadButton1_Click">
</telerik:RadButton>

C#:

protected void RadButton1_Click(object sender, EventArgs e)
{
    RadDatePicker1.Clear();
}

Thanks,
Shinu.

Hi,

Try the following
C#

protected void Button1_Click(object sender, EventArgs e)
{
    RadDatePicker1.Clear();
    RadDatePicker1.DateInput.Clear();
}

Thanks.

Hi,

This does not work for me. I have a standard RadDatePicker control and want to reset the values to null or blank when the clear button is pressed.
I select  a date using the calendar and then click the clear button which has the following code in the Click event:

RadDatePicker1.Clear();
RadDatePicker1.DateInput.Clear();

But nothing happens. The click event fires correctly but the RadDatePicker selected date remains in the text box.
Why is the date value not being cleared?

Regards,

Shuja

I figured it out. The above code does work.
The control references in my RadAjaxManager didn't seem to work, for some reason. I cleared them and used the Ajax Manager Configuration tool in design mode and that seemed to do the trick. The controls are now being refreshed with AJAX and the reset values are working correctly for the radDatePicker control.

Thanks,

Shuja

This should work but still doesn't. It works if I trigger the job from someplace else but if I trigger it from a closed drop down, nothing. Think it's time to dump Telerik.

Hello Matt,

 

I'm sorry to hear that this kind of issue left such an impression on you about Telerik tools. Generally, we strive not only to sky rocket the development time and quality of our users, but also to ease up handling issues by providing the necessary support and resources in the process.

And check the love we are still showing Web Forms by taking a look at the recent release notes of the controls to see how many improvements and stabilization efforts were made:
https://www.telerik.com/support/whats-new/aspnet-ajax/release-history/ui-for-asp-net-ajax-r3-2019-(version-2019-3-917)
https://www.telerik.com/support/whats-new/aspnet-ajax/release-history/ui-for-asp-net-ajax-r1-2020-(version-2020-1-114)

As for the specific tech question, the following configuration works on my side:

        <telerik:RadDatePicker runat="server" ID="RadDatePicker1" SelectedDate="2/2/2020">
        </telerik:RadDatePicker>
        <asp:Button ID="Button2" runat="server" Text="Clear Picker" OnClick="Button2_Click" />

C#:

    protected void Button2_Click(object sender, EventArgs e)
    {
        RadDatePicker1.Clear();
    }

Could you try it out on your side and verify that it works properly? Otherwise, you can temporarily disable AJAX and check for any hidden script errors:
