Combo box not updating value 17.4.0.46

[Krasimir Ivanov]

Hello,

When using the combo box componet I am binding a value that is not being updated when typing in the field. The code is:

  <EjsComboBox AllowCustom=@true

                                     AllowFiltering=@true

                                     TValue="string"

                                     @[email protected]

                                     [email protected]()

                                     Placeholder="Select an user">

                            <ComboBoxFieldSettings Text="Text" Value="Text" />

</EjsComboBox>  

The ReporterName property is not being updated

Hi Sureshkumar,

It seems this issue is also affecting other controls which implement the ValueChanged event. I have had the same issue with DropDownLists, NumericTextBox and a few other controls too. It also seems that calling StateHasChanged() seems to disable all further change events on a particular control. @bind-Value works first time only and only updates the underlying variable once. ValueChanged also has the same issue, so for my NumbericTextBox I tried ValueChange - see below. If you put a breakpoint on the "AssignmentID=...." line it will break every time. If you uncomment the StateHasChanged(); line, it will break the first time you change the value, but never again after that. As I stated earlier, this affects DropDownList and other controls as well.

<EjsNumericTextBox TValue="int?" Format="#" ShowSpinButton="false" Placeholder="Assignment ID" FloatLabelType="FloatLabelType.Always" Value="@AssignmentID">
    <NumericTextBoxEvents TValue="int?" ValueChange="AssignmentIDChanged" />
</EjsNumericTextBox>

@code

(

    public int? AssignmentID;

    protected void AssignmentIDChanged(Syncfusion.EJ2.Blazor.Inputs.ChangeEventArgs args)
    {
        AssignmentID = (int?)(args.Value == 0 ? (double?)null : args.Value);
        //StateHasChanged();
    }

)
