Trying to bind Readonly property of EjsDatePicker

[David Saylor]

I'm trying to bind the Readonly property of a date picker inside of an accordion item to another boolean property.  When I do that, via the code below, the EjsDatePicker does not render on screen, AND the content template of the accordion item also does not render.  When I take that one attribute out (highlighted), both render successfully.

Can you tell what is wrong, or if this is a control issue?

        <EjsAccordion>

            <AccordionItems>

                <!--Status-->

                <AccordionItem>     

                    <HeaderTemplate>

                        <div>Record Status <label style="font-size:smaller;">@items.ValueNameWithCommas</label></div>

                    </HeaderTemplate>

                    <ContentTemplate>

                        <ul id="status">

                            @foreach (var item in items)

                            {

                            <EjsCheckBox Label=@item.Description @bind-Checked=@item.IsSelectedBool CssClass="e-primary"></EjsCheckBox>

                            }

                        </ul>

                    </ContentTemplate>

                </AccordionItem>

                <!--Date Range-->

                <AccordionItem Header="Date Range">

                    <ContentTemplate>

                        <EjsDatePicker Placeholder="Start Date" @bind-Value=@this.DataElement.RangeStart @bind-Readonly=@this.DataElement.SearchAllDatesBool></EjsDatePicker>

                    </ContentTemplate>

                </AccordionItem>

            </AccordionItems>

        </EjsAccordion>

Hi David,  

Greetings for Syncfusion support.  

We have validated your reported issue with shared code snippet. You have used incorrect property(@bind-Readonly) bind to DatePicker component. The Readonly property is one-way binding, so no need to use @bind for this property. We have prepared sample based on shared code snippet. Please find the sample and code snippet for your reference.
