I'm using telerik pro ui library in nativescript, I struggled in changing the bottom line color of text field when focused to be appropriate to design
I want to change the blue default color of line
The text field currently rendered as shown in the following image
The code of template view is
<GridLayout rows="100, *" row="1" class="m-x-10 m-t-75">
                <RadDataForm #loginFormElement [source]="loginForm" [isReadOnly]="isLoading" row="0" class="fa">
                    <TKEntityProperty tkDataFormProperty name="email" displayName="" hintText="example@gmail.com" imageResource="res://fa_user" required="true"
                        index="0">
                        <TKPropertyEditor class="fa" tkEntityPropertyEditor type="Email">
                            <TKPropertyEditorStyle tkPropertyEditorStyle labelHidden="true"  labelWidth="0"></TKPropertyEditorStyle>
                        </TKPropertyEditor>
                        <TKNonEmptyValidator tkEntityPropertyValidators errorMessage="البريد الالكتروني مطلوب"></TKNonEmptyValidator>
                        <TKEmailValidator tkEntityPropertyValidators errorMessage="البريد الالكتروني غير صحيح"></TKEmailValidator>
                    </TKEntityProperty>
                    <TKEntityProperty tkDataFormProperty name="password" displayName="" hintText="كلمة المرور" required="true" index="1">
                        <TKPropertyEditor tkEntityPropertyEditor type="Password">
                            <TKPropertyEditorStyle class="fa" tkPropertyEditorStyle labelHidden="false" labelTextSize="18" labelFontName="FontAwesome"
                                labelPosition="Left" labelWidth="30" labelTextColor="#999"></TKPropertyEditorStyle>
                        </TKPropertyEditor>
                        <TKNonEmptyValidator tkEntityPropertyValidators errorMessage="كلمة المرور مطلوبة"></TKNonEmptyValidator>
                    </TKEntityProperty>
                </RadDataForm>
                <Button class="form-submit-button bg-light-green m-y-25 m-l-5 m-r-5" [text]="'تسجيل دخول'" (tap)="onSigninButtonTap()" row="1"></Button>
            </GridLayout>
