I try to embed to masked Text Box into In Place Editor:
<SfInPlaceEditor Mode="RenderMode.Inline" Type="InputType.Text" TValue="string" Value="@ProfileUser.CardNo" CssClass="w-100"
EmptyText="@StringLocalizer["Enter discount card number..."]" ShowButtons="false" ActionOnBlur="ActionBlur.Ignore" SubmitOnEnter="true">
<InPlaceEditorEvents TValue="string" OnActionBegin="OnCardNoChanging" />
<InPlaceEditorTemplates>
<Template>
<SfMaskedTextBox Placeholder="@(StringLocalizer["Enter discount card number..."])" ShowClearButton="true"
@bind-Value="@ProfileUser.CardNo" Mask="9999999999999999" />
</Template>
</InPlaceEditorTemplates>
</SfInPlaceEditor>
When I try to enter any new sign, In Place Editor turn off its Edit mode without saving.
