[Solved] NumericTextBox throws as error on AddModelError

[Marin]

When is added model error for NumericTextBox, NullReference error message is thrown in InputComponentExtensions.cs

public static string GetAttemptedValue<T>(this IInputComponent<T> instance) where T: struct
{
    ModelState state;
    if (instance.ViewContext.ViewData.ModelState.TryGetValue(instance.Name, out state))
    {
            return state.Value.AttemptedValue;
     }

    return string.Empty;
}

state.Value is null. I add checking and now is working fine.

public static string GetAttemptedValue<T>(this IInputComponent<T> instance) where T: struct
{
    ModelState state;
    if (instance.ViewContext.ViewData.ModelState.TryGetValue(instance.Name, out state))
    {
        if (state.Value != null)
        {
            return state.Value.AttemptedValue;
        }
    }

    return string.Empty;
}

Hello Marin,

 
This is a known issue, which I am glad to inform you is already fixed in the latest internal build of Telerik Extensions for ASP.NET MVC.

Best wishes,
