<DxTextBox Text="Some text" TextChanged="@((newValue) => OnTextChanged(newValue))"></DxTextBox>
<DxButton Enabled="@IsEnabled">Update Text</DxButton>

@code {
    bool IsEnabled = true;

    void OnTextChanged(string newValue) {
        if (!string.IsNullOrEmpty(newValue)) {
            IsEnabled = false;
        } else IsEnabled = true;
    }
}
